Jeanne Lee Crews

Last updated

Jeanne Lee Crews (born 1940) was an American aerospace engineer at NASA, and also one of the first female engineers to join the agency. [1] She retired in November 2002 and is now living in Satellite Beach, Florida. In order to protect spacecraft from debris, she designed a "flexible multi-shock shield to protect spacecraft from debris," [1] which is still in use on the International Space Station today. Jeanne Lee Crews is also one of the first women at NASA to participate on a zero-G flight. [1] She has more recently been working on a way to gather and accumulate orbital debris, through a large balloon that will return to Earth once full. [1] Jeanne Lee Crews has been awarded with Aerospace Lifetime Achievement Award, the NASA Exceptional Service Medal, and the NASA Exceptional Achievement Medal. [1]

Early life

Jeanne Lee Crews was born in 1940. [2] [3] Jeanne Lee Crews's interest in space and science began when she was about 8 years old. She loved all kinds of science. Jeanne first believed she would be an astronomer. [4] Her father was a pilot in the Air Force. Both her mother and father were supportive of her love for science and supplied her with telescopes, microscopes, or anything she had an interest in. [4] Sputnik and the space race ignited her passion for space even further. [4] Jeanne began acquiring her college degree at the University of Texas with a major in Aerospace engineering. Jeanne was one of ten engineering freshman who was invited to take a physical chemistry course with graduate students. [4] She then finished getting her B.S. in aerospace engineering at the University of Florida. [4]

In September 1964, Jeanne was hired at NASA as an engineer. She was one of the first women engineers hired there. Jeanne expressed in an oral interview, "... I really had to work hard to get the responsibility. Everybody wanted to hold my hand. Now, I know that sounds, “Well, isn’t that nice?” But it isn't when you're really trying to prove yourself... I didn't blame them; I really didn't. They just didn't know how to handle me." [4] Once hired, she went to Houston, Texas.

Career at NASA

Crews worked on the Apollo landmarks as the zero gravity flights were taking place. She later worked on projects such as Skylab. Jeanne took flight in the zero gravity plane. Other than nurses who were asked to come on the plane, Jeanne was one of the first women on the zero-G plane. [4]

Jeanne created the hyper velocity laboratory where her work was focused on protecting Spacecraft and satellites from impacts from space debris and meteoroids. [5] [6] It was evident by now that when a spacecraft collides with even minuscule pieces of space debris, which are traveling at orbital speeds, the damage and impact could be severe, [1] and even life-threatening. The multi shock shield was a project Jeanne invented. [7] She first started out by creating a small hydrogen fueled gun in order to test materials. She used the gun to see how well the spacecraft could withstand high-velocity impacts. After multiple tests, Jeanne soon realized that the aluminum that is used normally to build spacecraft was especially vulnerable to debris collisions. [8] The solution she thought of was a shield comprising "multiple layers of ceramic fabric, open-cell foam and other materials." [1] This layered shield repeatedly shocked impacting particles in order to protect the spacecraft. [3] She created a shield from fabric to make it weigh less, yet have more strength. This is known as the flexible multi-shock shield. [3] [9] It was patented and belongs to NASA [10] and is still in use today on the International Space Station. [11] The shield Is designed to protect from impacts of debris with densities of 2.7 g/cm3, as well as impact velocities of 16 km/s. [12]

While working at NASA, Crews was able to fly some of the training simulators. She could do so as long as no reporters saw her get in or out of the simulators. Donald K. Slayton told Jeanne she should not be photographed because they did not want anyone thinking that there was a woman astronaut. [4]

More recently, Lee Crews has been working on a method to collect orbital debris. Her design is a very large balloon, between 1 and 10 km in diameter, made of ceramic fabric that will "shock whatever has struck the craft so much that is vaporized. If you have four or five sheets, one behind the other, you shock it repeatedly and raise energy levels so much you get more vaporization and it gets smaller and smaller." [1] Once the balloon is full, it is returned to Earth

Throughout Jeanne's years at NASA, she was an engineer, contract monitor, and a researcher at Space and Life Sciences. [4] Towards the end of her career, she was the Assistant to the Division Chief. [4] In November 2002, Crews retired from NASA.

Awards

In 1990, Jeanne was awarded a Patent For the multi-shock shield along with her co-inventor Burton G. Cour- Palais. [13] In 1992, she was awarded the Tech Brief Award, along with Cour- Palais and Eric Christiansen. [13] She was also awarded the Women in Aerospace Lifetime Achievement Award. [13] In 1993, she won the Board Award, otherwise known as a NASA Headquarters Space Act Award, as well as the NASA Exceptional Service Medal. [13] In 1995, she won the NASA Exceptional Achievement Medal. That same year, she was also awarded the Board Award for Debris Shield, Board Award for Weight Reduction Design, and the Patent Award, again. [13] In 1998, she won the Tech Brief Award, again. In 1999, she won the Silver Snoopy Award as well as the Tech Brief Award. in 2006, Jeanne was honored for "Far-Reaching Inventions." [13]

Atmospheric entry is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite. There are two main types of atmospheric entry: uncontrolled entry, such as the entry of astronomical objects, space debris, or bolides; and controlled entry of a spacecraft capable of being navigated or following a predetermined course. Technologies and procedures allowing the controlled atmospheric entry, descent, and landing of spacecraft are collectively termed as EDL.

Space debris are defunct human-made objects in space—principally in Earth orbit—which no longer serve a useful function. These include derelict spacecraft—nonfunctional spacecraft and abandoned launch vehicle stages—mission-related debris, and particularly numerous in Earth orbit, fragmentation debris from the breakup of derelict rocket bodies and spacecraft. In addition to derelict human-made objects left in orbit, other examples of space debris include fragments from their disintegration, erosion and collisions or even paint flecks, solidified liquids expelled from spacecraft, and unburned particles from solid rocket motors. Space debris represents a risk to spacecraft.

The Whipple shield or Whipple bumper, invented by Fred Whipple, is a type of spaced armor shielding to protect crewed and uncrewed spacecraft from hypervelocity impact / collisions with micrometeoroids and orbital debris whose velocities generally range between 3 and 18 kilometres per second. According to NASA, the Whipple shield is designed to withstand collisions with debris up to 1 cm, which helps to mitigate the Kessler syndrome.

Space environment is a branch of astronautics, aerospace engineering and space physics that seeks to understand and address conditions existing in space that affect the design and operation of spacecraft. A related subject, space weather, deals with dynamic processes in the solar-terrestrial system that can give rise to effects on spacecraft, but that can also affect the atmosphere, ionosphere and geomagnetic field, giving rise to several other kinds of effects on human technologies.

<span class="mw-page-title-main">Kessler syndrome</span> Theoretical runaway satellite collision cascade that could render parts of Earth orbit unusable

The Kessler syndrome, proposed by NASA scientist Donald J. Kessler in 1978, is a scenario in which the density of objects in low Earth orbit (LEO) due to space pollution is high enough that collisions between objects could cause a cascade in which each collision generates space debris that increases the likelihood of further collisions. In 2009 Kessler wrote that modeling results had concluded that the debris environment was already unstable, "such that any attempt to achieve a growth-free small debris environment by eliminating sources of past debris will likely fail because fragments from future collisions will be generated faster than atmospheric drag will remove them". One implication is that the distribution of debris in orbit could render space activities and the use of satellites in specific orbital ranges difficult for many generations.

An aeroshell is a rigid heat-shielded shell that helps decelerate and protects a spacecraft vehicle from pressure, heat, and possible debris created by drag during atmospheric entry. Its main components consist of a heat shield and a back shell. The heat shield absorbs heat caused by air compression in front of the spacecraft during its atmospheric entry. The back shell carries the load being delivered, along with important components such as a parachute, rocket engines, and monitoring electronics like an inertial measurement unit that monitors the orientation of the shell during parachute-slowed descent.
