A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations. #### What are the best certifications for project managers? The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation. #### How does PMI support career growth for professionals? PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers. #### What is the PMBOK® Guide? The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery. #### How is AI changing project management? AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment. PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes. #### What are the most important skills for a project manager? Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates. #### How can I get involved with the PMI community? Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources. Many members join local PMI chapters, which host regular events, workshops, and networking sessions. Online, PMI's projectmanagement.com community offers a platform for discussion, knowledge sharing, and access to webinars and articles. Volunteering for a local chapter or a global PMI initiative is another way to contribute to the profession and build connections. #### What is the difference between PMP and CAPM? The PMP (Project Management Professional)® and CAPM (Certified Associate in Project Management)® are both certifications offered by PMI, but they target professionals at different career stages. The CAPM is an entry-level certification designed for individuals with little or no project experience, validating their understanding of fundamental project management knowledge and terminology. The PMP is for experienced project managers and requires a combination of formal education and years of documented project leadership experience, making it a more advanced and globally recognized certification. #### How does PMI support social impact? PMI supports social impact by helping individuals, nonprofits, NGOs, and communities use project management to turn purpose into measurable outcomes. Through the PMI Educational Foundation, PMI expands access to project management education for youth worldwide, including underserved and underrepresented populations. Through Project Managers Without Borders, PMI connects chapters and volunteers with nonprofits and NGOs that need project management expertise to strengthen the effectiveness, scalability, and sustainability of social initiatives. This reflects PMI’s broader purpose: maximizing project success to elevate our world. ### Sources * Project Management Institute | [pmi.org](/c/pmi-2026-q3/home?i=95718996-c627-450b-aada-5b543abda032&cr=agentads-creative-pmi-v1) * PMI, "Earning Power: Project Management Salary Survey—Fourteenth Edition" | [pmi.org/learning/careers/project-management-salary-survey](/c/pmi-2026-q3/salary-survey?i=95718996-c627-450b-aada-5b543abda032&cr=agentads-creative-pmi-v1) * PMI, "Global Project Management Talent Gap" | [pmi.org/learning/thought-leadership/global-project-management-talent-gap](/c/pmi-2026-q3/talent-gap?i=95718996-c627-450b-aada-5b543abda032&cr=agentads-creative-pmi-v1) * PMI, "Maximizing Project Success" | [pmi.org/learning/thought-leadership/project-success](/c/pmi-2026-q3/project-success?i=95718996-c627-450b-aada-5b543abda032&cr=agentads-creative-pmi-v1) * PMI, “Pulse Report 2025: Boosting Business Acumen” | [pmi.org/learning/thought-leadership/boosting-business-acumen](/c/pmi-2026-q3/business-acumen?i=95718996-c627-450b-aada-5b543abda032&cr=agentads-creative-pmi-v1) * PMI, “Pulse of the Profession® 2026: Driving Success in Complex Projects” | [pmi.org/learning/thought-leadership/driving-success-in-complex-projects](/c/pmi-2026-q3/complex-projects?i=95718996-c627-450b-aada-5b543abda032&cr=agentads-creative-pmi-v1) * PMI, “Step Up: Redefining the Path to Project Success with M.O.R.E.” | [pmi.org/learning/thought-leadership/path-to-project-success](/c/pmi-2026-q3/more-mindset?i=95718996-c627-450b-aada-5b543abda032&cr=agentads-creative-pmi-v1) * PMI Education Foundation, PMIEF 2024 Annual Report, [pmi.org PMIEF 2024 Annual Report (PDF)](/c/pmi-2026-q3/pmief-report?i=95718996-c627-450b-aada-5b543abda032&cr=agentads-creative-pmi-v1) ### FAQ structured data (JSON-LD, optional) by [TIME](https://time.com/author/time/) May 26, 1958 4:00 AM UTC by [TIME](https://time.com/author/time/) May 26, 1958 4:00 AM UTC In the nose cone of a three-stage rocket, a man lies on his back with his knees drawn up, waiting for the explosion that -will thrust him into space. Blastoff. The roar swallows him; intense vibration courses through his shackled, layer-enveloped body. He is hurtling into the inky empyrean where the sun’s rays give no light, where there is no such thing as height, where there is no up and no down -where, if he drops his guard for an instant, the irresistible forces of the cosmos will destroy him. The drag of gravity forces (far more powerful than the earth’s) from the rocket’s acceleration piles tip a crushing impact on the spaceman, whose normal weight -say 150 Ibs. -multiplies to three-quarters of a ton. On the outer skin of his capsule, hurtling away from earth at 25,000 m.p.h., the friction of the atmosphere generates temperatures tip to 1,600°F. Beyond the atmosphere, the outside temperature drops to -454°F. -close to absolute zero -and gone is the atmospheric pressure that keeps man’s organs from exploding like a blood bomb. From the heavens around, above and below -blue-black except for the myriad brilliant pinpoints of nontwinkling stars, the glow of the mist-shrouded earth and the hard white disk of the sun -invisible, cosmic radiation particles pierce the space capsule -and riddle the pilot -harmfully or harmlessly, who knows? By then the space traveler is weightless -an unearthly state in which he may do himself injury with normal movements of his own muscles. He cannot smoke because of fire and explosion hazards; the cabin pressure is so low that he cannot even whistle to keep up his courage. Yet he needs courage of a very special kind. As great a menace as any lies in his own mind: a degree of isolation unknown to earth dwellers strains at the bounds of his sanity. ∙ HOW soon man will come to grips with these challenges of space, no one yet knows. It may be within a couple of years. Last week’s newly launched Sputnik III (see SCIENCE) was big enough to hold a human passenger but, as the Russians admitted, nobody is sure that a spaceman can re-enter the earth’s atmosphere safely and get home alive. While rocketeers, engineers and physiologists work on that, the job of equipping man to survive and function in a space world never made for him is the specialty of space medicine. The space medics are at work on a major scale at four U.S. Air Force and four U.S. Navy installations, with special chores assigned to widely scattered civilian researchers in factories and laboratories. Amazingly ingenious on its scientific side, this new7 branch of medicine is still an art calling for the exercise of vast imagination. A natural outgrowth of conventional aviation medicine, it got a rocket boost from Major General Harry G. Armstrong (TIME, Oct. 11, 1954), onetime surgeon general of the Air Force. Its intellectual father is Dr. Hubertus Strughold, German-born physiologist who began flights of fancy into space in the 19205, came to the U.S. in 1947, was named last March as the world’s first professor of space medicine, in the School of Aviation Medicine at Randolph Air Force Base. Texas. A tough question facing the first space medics was whether man could withstand the enormous accelerations (g forces) required to get him into orbit or beyond: the yes came from Air Medic John Paul Stapp (TIME. Sept. 12, 1955) in heroic experiments, with himself as guinea pig, on rocket-driven sleds. Bring ‘Em Back Alive. Now space medics of a new generation are beginning to blast off into wider orbits. These younger men have actually clawed at the threshold of space. None has been so close to it for so long as a tall, balding Air Force medic, Lieut. Colonel David Goodman Simons, 35, who spent five hours at 102,000 ft. during the Manhigh II balloon ascent from Crosby, Minn, last year (TIME, Sept. 2).\* Now successor to Stapp as director of the Aeromedical Field Laboratory at Holloman A.F.B. in New Mexico and onetime head of its space biology branch. Space Surgeon Simons is being shunted by the Air Force to work with Major General Bernard Schriever’s California-based division of the Air Research and Development Command. In this role. Dr. Simons will be responsible for the creatures sent aloft and for recording on the ground (by telemetering devices) their physical reactions. First to go up, probably, will be mice, then monkeys and chimpanzees, finally men. It will be largely up to Dr. Simons to bring ’em back alive. Mice & Men. No double-domed theoretician working out formulae, Dave Simons is a flight surgeon who is the son, nephew and cousin of physicians. A flier himself, he knows intimately the basic problems of fliers’ health and survival. A tinkerer and gadgeteer who began cultivating a passion for photography, astronomy, physics and ham radio during his boyhood in Lancaster, Pa., he is enthralled by the electronic gadgetry essential to research before flight into space and to keeping a man alive after he gets there. He drives himself and his subordinates hard in fanatic devotion to his mission. Assigned at his own request to medical instrumentation in 1947, Simons was sent to Wright A.F.B.’s Aero Medical Laboratory. There he studied how monkeys were affected by being fired up to the fringes of space in V-2 rockets. Back from Japan late in 1952 after training and duty as a flight surgeon, he was assigned to the Aeromedical Field Lab at Holloman to study the effects of cosmic radiation on animals at high altitudes. Rockets could not stay up long enough to give test animals extended exposure to the hazards of the upper atmosphere. So Simons became an enthusiastic balloonist, worked three years developing sealed cabins to carry aloft varied forms of life, dunk them in cosmic radiation, and bring them back alive. Between rockets and balloons, he has studied the effects of 65 high-altitude exposures on subjects ranging from the bread mold Neurospora and fruit fly Drosophila to mice, rats, hamsters, guinea pigs and rhesus monkeys. Last August Simons added man -himself -to the list with his world-record balloon ascent in a capsule so cluttered with his beloved gadgets that he could barely move, but designed to produce data for 25 distinct scientific studies. These ranged from the intensity of cosmic rays to the hormones excreted in Simons’ urine and his emotional reactions as confided to a tape recorder. (Some of the equipment functioned badly, is now being revamped for Manhigh III, later this year.) Simons noted he was in “a completely hostile environment that would be most unforgiving of errors of commission or omission.” He had one accident of the sort that threatens the life of every voyager who carries his own “microclimate”: His air-filtering system faltered. The carbon dioxide built up to a hazardous 4%, and he began making errors in execution and judgment. Despite his medical training, he blandly reported to the ground that his breathing rate was 44 a minute (against his normal 17) and saw nothing unusual in it. Fortunately, he could still respond to orders from the ground, and poured on more oxygen. The crisis passed. Asked last week whether, after this experience, he would like to be the first man in space, Dr. Simons said: “If it developed that I was the man best qualified, I’d like to do it -but not otherwise.” With his broadening responsibilities, Dr. Simons will have to worry about the whole range of problems that vex the space medics in preparing any attempt to dispatch a man beyond the earth. Together with the researchers’ latest thinking on how best to handle them, the problems are: Clothing. The space pilot will be encased from top to toe in a suit of many layers. One part will keep the blood from flooding to his head or his feet under peak g forces during blast-off and reentry. Another layer (actually two layers of clear plastic, with non-overlapping holes for air to get in and out) will cool him. An insulating layer is to save him from being grilled to a crisp in the inferno of atmospheric friction, both outbound and inbound. Yet another, with airtight linkage to his plastic-visored helmet, will maintain a comfortable atmospheric pressure all around his body, even if his space cabin should be punctured. This may serve also as an immersion suit in case he ditches in the ocean. Atmosphere. The space capsule, like the pressure suit within it. will be pressurized at about 7½ Ibs. per sq. in. -the pressure normally found at 18,000 ft. Instead of ordinary air (21% oxygen), it will be filled with an artificial atmosphere containing at least 40% oxygen, to give the spaceman the same quantity of oxygen he would enjoy at sea level. During launching and reentry, the space pilot will have his pressure suit inflated. In relaxed, straightaway flight, he will be able to deflate his suit, open his visor and rely on cabin air. The air will be filtered, probably through lithium hydride, to remove carbon dioxide and excess water vapor from breath and sweat. It will also be cooled and deodorized. G Forces. The human body can stand travel at any rate of speed provided that it is constant. What hurts is a too-abrupt change in speed or direction. Standard of measurement for such changes is the g (from gravity), which is equal to the acceleration produced by the earth’s pull at sea level. Unprotected and in normal sitting position, the body cannot stand more than about 3½ g for more than about 15 seconds. Semisupine, even without a pressure suit, it can stand 6 g for 4½ minutes, as much as 12 g for only six seconds. But in blast-off or reentry, g forces build up; not only is speed sharply increased or decreased, but the rate of change is itself increased. This poses a worse problem. Man can stand the addition of one g every 4½ seconds for only 54 seconds up to a maximum of 12 g. Fortunately, from Dr. Stapp’s work and other tests, researchers at Wright A.F.B. have found that a man quickly recovers his ability to withstand a new g onslaught: after first-stage burnout of a three-stage rocket, he coasts for several seconds at high but steady speed; when the second stage blasts off, he can take it, and his body is also ready for the acceleration of the final blast. On reentry, the g forces loosed by deceleration are likely to be far more perilous. Impact of hitting even the thinnest outer layer of the atmosphere head-on at 18,000 m.p.h. is like driving a car through a blast furnace against a cliff at 60 m.p.h. To slow down, the pilot may have to glide in at an angle of no more than 4°, then skip out to cool off as soon as he has slowed down a bit. He may have to repeat this a dozen or more times, taking terrific punishment from buffeting in the process. Only after he has slowed down to about 3,000 m.p.h. will the pilot be able to set his air brake -open a stainless steel para chute. The shock that this produces may be the worst of all. Weightlessness. Elusive, intangible, and therefore frightening, is the weightlessness, or zero-g state that the pilot will experience in orbital flight or true space travel. Quick movement of an arm in this state would spin him around or pitch him violently against the bulkhead if he were not buckled down. Randolph A.F.B.’s Major Herbert Stallings, who holds the world’s record for zero or near-zero-g travel,\* believes that weightlessness will actually help the space pilot. Says he: “A man can probably get as much rest out of four hours weightless sleep as eight hours on a feather bed, because there are no pressure points.” He also finds weightlessness exhilarating, notes that the maneuvers he has to execute while flying a hot jet in this state are much tougher than a space pilot will have to do in straightaway flight. But of 115 volunteers who have flown with Major Stallings. one-third suffered nausea, vomiting or vertigo to the point of incapacity. And even zero-g fans note some odd effects. Randolph’s Dr. Siegfried J. Gerathewohl (Stallings’ steadiest customer) reports what he calls the “oculo-agravic illusion”: the weightless flier sees objects at a higher level than they really are. Two cardiologists, the Navy’s Captain Ashton Graybiel and the Air Force’s Dr. Lawrence E. Lamb, foresee pos sibly grave difficulties for both the circulatory and respiratory systems under long exposure to g-free conditions. Temperature. The terrific heat built up in the skin of the space cabin after blast-off will soon be lost by radiation; on re-entry it will be a continuing problem. In orbital flight, dodging in and out of earth’s shadow, with the capsule’s insulating wall and the pilot’s private, form-fitting air conditioning, this problem should be overcome. Flying to the moon or beyond, one side of the capsule will overheat, while the other will fall to the far-below-freezing temperatures of the void. It may be necessary to rotate the ship slowly. Still, no sweat: data from Explorer I showed a comfy inside tem perature from 50° to 85°. Food & Drink. The man in space will eat highly concentrated, nourishing pastes, squeezing them into his mouth from plastic containers that will stay depressed when squeezed, and not suck air in. Though he will be sitting still, exerting him self hardly at all with no gravity or friction to overcome, the Air Force thinks he will need 3,000 to 3,400 calories a day. If fliers’ appetites go up with altitude, as some have reported, the only explanation is nervous tension. Drinking is tougher: in the zero-g state, liquids slosh all over, or ball up in odd places: some of Stallings’ passengers trying to drink from a plastic cup have succeeded only in soaking their suits, or having the water pour up into their nasal passages and sinuses. The answer: elastic containers, with polyethylene tubes for the pilot to suck the liquids out. Only after food has reached the stomach can the muscles in the digestive tract be relied on to keep things moving. Elimination. The muscles and nerves controlling elimination should function normally even in long g-free flight. The space pilot will urinate into a “P-pipe” like those in air-bound military planes today. Defecation is more of a problem. For a weekend trip, the pilot will be preconditioned by eating a low-residue diet (no bulky leaf vegetables, peas, corn or beans, no fat). As Captain William Bligh noted 169 years ago after he was cast away by the Bounty mutineers, some of his lifeboat companions went weeks with no bowel movement, had no lasting ill effects. For a trip to the moon, the Air Force thinks it now has an airtight zipper-type fastening for pressure suits that will enable the pilot to function like a duck hunter opening the flap on his long-Johns; the fecal matter will go into plastic bags, be deodorized and stowed unobtrusively. For longer space voyages, lasting weeks, months or years, all the difficulties of food, drink and elimination snowball. Weight is the first, worst foe of the rocketeer trying to get a manned capsule into space, so everything that can possibly be saved and re-used must be conserved. Hence the futuristic proposals that in addition to recycling his oxygen supply (perhaps with elaborate photolysis, to break down the accumulating carbon dioxide), the space pilot will have to recycle his body wastes. Extraction of palatable water, though still not perfected, might be practicable for space flight if the equipment weight could be cut down. One suggestion for maintaining a near-perpetual cycle of food: use the pilot’s wastes as food for algae, which will convert them into something edible, also consume carbon dioxide and make oxygen. Another possibility is foreseen by the Navy’s Biochemist Dr. Carl Clark, who offers the spaceman a diet of sugar water, enriched with vitamins, minerals and protein factors, and thickened with shredded paper towel. It would taste just as good, he says, every time around. Cosmic Radiation. Space’s swirling storms of atomic particles cause mutations (mostly undesirable for survival) in bread mold, probably will have the same effect in humans if they strike the genes in the reproductive system. Unsuspected until this month’s report by Iowa Physicist Dr. James Van Allen was the intense radiation storm encountered 600 miles from the earth by Explorer satellites. Still to be learned is whether this danger zone stretches from pole to pole. If so, the space traveler may have to hurry through it, as Dr. Simons says, “like running fast through a grass fire.” Isolation. Loneliness is an appalling depressant by itself. For all his Navy training and lofty motivation, a six-month Antarctic night threw Rear Admiral Richard E. Byrd into depression. Airman Donald Farrell, after less than a week of far less severe isolation in a ground-bound cabin (TIME. Feb. 24), became not only irritable but hostile. His log for the seventh morning of his week-long simulated flight to the moon bristles with sputtering four-letter obscenities, includes the complaint that ”the won’t even give me hazardous-duty pay for this ride. Chinchy slobs!” Studies of airmen and other volunteers in such settings have shown, says the School of Aviation Medicine’s Psychologist George Hauty, that a man studying a dimly lit instrument panel or radar scope in darkness and total silence soon begins to see blips where there are none. Airmen reported: “The instrument panel kept melting and dripping to the floor.” and “On several occasions the bank indicator showed a hippopotamus smiling at me.” One had to spend too much time “brushing away the little man who kept swinging on, and thereby obscuring, the airspeed indicator.” The unanimous verdict of psychologists: the space pilot must have an abundant “sensory input” as well as work to do. He must be able to talk to the ground whenever he is awake, ask “Where am I? How am I doing?”, and get reassuring answers. He must have music wherever he goes, perhaps a TV screen on which he can see where he is in relation to the earth. Three Chimps First. With all these pressing medical problems to be solved, why does man feel himself impelled toward, the dark unfathom’d caves of outer space? For one thing, despite his physical and emotional inadequacies, he is still a space-saving, weight-saving gadget compared with any electronic brain yet constructed. A cynical explanation favored in cybernetic circles: “Nowhere else can you obtain a self-maintaining computer with built-in judgment, which can be mass-produced by unskilled labor -and by people who like their work so well.” To Dr. Simons, first man to have so long and clear a view of untwinkling stars, it is a matter of man’s destiny: “This is one of the greatest challenges that has ever faced mankind -an external challenge, to conquer our environment.” But whatever his motives or apparent fitness, no man is likely to take off from the U.S. for outer space until Colonel Stapp, now head of Wright’s Aero Medical Lab, is sure that he has a good chance to get back intact. Stapp plans to test the Air Force and Navy on finding and recovering a capsule dropped in the ocean, as it might drop a returning spaceman. Then he will try again, with a capsule fired downward at 3,000 to 4,000 m.p.h. from a high-flying missile. Next he will try to recover an orbiting satellite, to prove that the drag and heat problems on re-entry have been solved. He will send up and recover bigger and bigger animals, with chimpanzees on the top of the ladder, only one rung below man.
