Parachutes are plaguing space programs. SpaceX doesn’t like Parachutes. They are difficult to design, hard to package, and easy to damage. The larger the mass of the spacecraft, the more effort to slow down. Larger, more efficient, complex parachute systems are needed. Several failures have hit the industry over the last few years, including SpaceX Crew Dragon, ESA ExoMars, Boeing CST-100, and the NASA Orion to name a few.

How do parachutes work and why are they hard?

The idea of a parachute is simple. All falling objects fall the same when under the same conditions… that is so long as no outside force is exerted on it. So two objects dropped from the same altitude, one a feather and hammer will fall equally. Don’t believe me? NASA tested it on the Moon. During Apollo 15 moon walk, Commander David Scott performed a live demonstration for the television cameras. Commander Scott did the Apollo 15 Hammer and Feather test. He held out a geologic hammer and a Falcon feather and dropped them at the same time. Because there is not an atmosphere on the Moon, they were essentially in a vacuum. With no air resistance force, the feather fell at the same rate as the hammer. Ironically, Apollo 15 had a second demonstration of falling objects when one of the parachutes failed to function as planned.

On Earth, and any other planet with an atmosphere, air acts as a resistance force for an object moving through it. We can get more air resistance force by increasing the surface area. Depending on the shape of the object, it’s orientation, and the amount of resistance will increase, and therefore slow the object down. Unbalanced and uncorrected resistance can cause the object to start to turn, twist and tumble. A parachute system is deployed to generate air resistance from the atmosphere. (note that the thicker the atmosphere the more resistance) Parachutes designed for use on Earth will not be the same as a parachute designed for Mars.

Part 2 of the Life in Space with COVID19 we will delve into Crew demo-2 where NASA and SpaceX are planning a launch within two months. There are a lot of pre-launch milestones and activities to cover to ensure a safe flight for the Astronauts. If anything goes wrong, there are lives at stake. Now NASA and SpaceX have to contend with another potential setback, COVID19 pandemic. (Click here for part I)

In Part I of why COVID19 pandemic is bad timing for the Space industry, we covered that issues happen because the relationship between complexity, risk, schedule and cost for space missions was not balanced.

WestEastSpace mapped out NASA locations on a map of COVID19 impacted areas of USA from www.usafacts.org as of March 23rd, 2020With the launch window for NASA’s Mars Perseverance rover opening in a little less than four months, there are nearly daily pre-launch milestones to complete the rover pre flight activities at the Kennedy Space Center in Cape Canaveral, Florida. Tight schedules on complex missions usually do not mix well. Now NASA has to contend with another challenge. COVID19.

NASA Leadership Assessing Mission Impacts of Coronavirus

The world has come to a standstill and is in the grasps of the COVID-19. The world stock markets have come crashing down 30% as supply chains and companies attempt to deal with government response and public fear. Airlines and hotels have had to contend with decreased travel and lodging requirements. Logistics is impacted as factories in various countries deal with increased difficulty and requirements to obtain goods. Factories are closed leading to shortages for truckers, material movers, cargo agents, and other occupations directly involved in moving goods. Companies shift to working remotely in an attempt to comply with government guidance in attempts to minimize the impact of the virus. One Mars mission has already been sidelined because of COVID19. NASA also needs to contend with these challenges.

Soyuz creeping up in cost

NASA has been dependent on Russia for transport to and from the ISS. Over time the cost of seats on the Soyuz crew vehicle have risen.

The Roscosmos’s Soyuz vehicle has been ferrying crew to the International Space Station since November 2000. Originally Soyuz was designed to carry cosmonauts to the Moon, however was repurposed to be the main transport vehicle for Russia over the years. The Soyuz spacecraft is capable of carrying three crewmembers at a time and is certified to remain docked with the ISS for a maximum of 200 days and is launched from the Baikonur Cosmodrome launch site.

Until the NASA Commercial Crew Program (CCP) is completed, Roscosmos remains the sole option for transporting astronauts to and from the ISS. At all times, at least one of the Soyuz spacecraft is docked at the International Space Station serving as an emergency lifeboat or escape pot should evacuation be needed. Typically two Soyuz capsules are docked at the ISS which allows up to six astronauts to remain on the International Space Station. The limit of six astronauts is established by the number of seats available for evacuation.

Dr. Ezekiel Emanuel, an American oncologist and bioethicist who is senior fellow at the Center for American Progress as well as Vice Provost for Global Initiatives at the University of Pennsylvania and chair of the Department of Medical Ethics and Health Policy, said on MSNBC on Friday, March 20, that Tesla and SpaceX CEO Elon Musk told him it would probably take 8–10 weeks to get ventilator production started at his factories (he’s working on this at Tesla and SpaceX).

O.o yayyyyyyyyyyyyy.

When it comes to space, there’s a problem with our human drive to go all the places and see all the things. A big problem. It’s, well, space. It’s way too big. Even travelling at the maximum speed the Universe allows, it would take us years to reach our nearest neighbouring star.

But another human drive is finding solutions to big problems. And that’s what NASA engineer David Burns has been doing in his spare time. He’s produced an engine concept that, he says, could theoretically accelerate to 99 percent of the speed of light — all without using propellant.

Essentially this can lead to euclidean geometry in programming essentially allowing near infinite decompression either in programming or in devices or even spaceships.

In physics and mathematics, in the area of vector calculus, Helmholtz’s theorem,^[1][2] also known as the fundamental theorem of vector calculus,^{[3][4][5][6][7][8][9]} states that any sufficiently smooth, rapidly decaying vector field in three dimensions can be resolved into the sum of an irrotational (curl-free) vector field and a solenoidal (divergence-free) vector field; this is known as the Helmholtz decomposition or Helmholtz representation. It is named after Hermann von Helmholtz.^[10]

As an irrotational vector field has a scalar potential and a solenoidal vector field has a vector potential, the Helmholtz decomposition states that a vector field (satisfying appropriate smoothness and decay conditions) can be decomposed as the sum of the form − ∇ ϕ + ∇ × A {\displaystyle -\nabla \phi +\nabla \times \mathbf {A} }, where ϕ {\displaystyle \phi } is a scalar field called “scalar potential”, and A is a vector field, called a vector potential.
