Godspeed, Uhura: A Bit of Star Trek’s Nichelle Nichols Will Go to Space

Nichelle Nichols, who blazed a trail for Black actors as Lieutenant Uhura on the original “Star Trek,” never got to go to space while she was alive — but her ashes and her DNA are due to reach the final frontier as early as this year.

The symbolic samples are scheduled to fly beyond the moon, along with the ashes of other dearly departed Star Trek pioneers such as James Doohan (“Scotty”); Majel Barrett Roddenberry (“Nurse Chapel”); the TV series’ creator, Gene Roddenberry; and visual-effects wizard Douglas Trumbull.

To top it all off, Nichols’ memorial journey will begin with the launch of a Vulcan rocket. “I’m sure she would have much preferred to go on the shuttle,” said her son, Kyle Johnson, “but this was a pretty close second.”

The “Enterprise” memorial mission is being organized by Houston-based Celestis, which has been making arrangements to fly its customers’ cremated remains for a quarter-century. A gram of Nichols’ ashes, plus DNA samples taken from her and from Johnson, will be among the secondary payloads for United Launch Alliance’s first Vulcan Centaur mission, set for no earlier than December.

Many Astronauts Never Recover all of their Bone Density after Returning to Earth

In his book, Endurance, astronaut Scott Kelly described the arduous task of readjusting to life on Earth after spending a year in space. As part of NASA’s Twins Study, Kelly lived and worked aboard the International Space Station (ISS) while his identical twin (astronaut Mark Kelly) remained on Earth. While the results of this study revealed how prolonged exposure to microgravity could lead to all manner of physiological changes, the long and painful recovery Kelly described in his book painted a much more personal and candid picture.

As it turns out, astronauts who spend extended periods in space may never fully recover. At least, that is the conclusion reached by an international team led by the University of Calgary after they assessed the bone strength of multiple astronauts before and after they went to space. They found that after twelve months of recovery, the astronaut’s bones had not regenerated completely. These findings could have significant implications for proposed future missions, many of which involve long-duration stays in space, on the Moon, and Mars.

Shenzhou-14 Astronauts Begin Their Mission of 6 Months in Space

The Shenzhou-14 mission, carrying three Chinese astronauts, docked successfully earlier this week with the Tiangong-3 space station. During their six-month mission on board the station, the new crew hopes to continue work on construction of the orbital Chinese outpost, which will be about one-fifth the size of the International Space Station.

NASA Will Rent Future Spacesuits From Longtime Supplier and Newcomer

NASA has struck deals with two commercial teams to provide the spacesuits destined for use when astronauts return to the moon by as early as 2025 — and there’s an extra twist that might have sounded alien to the Apollo moonwalkers a half-century ago. This time, NASA won’t own the suits.

Extended Trips to Space Alter the Brains of Astronauts

Going to space changes a person. We’ve known that ever since NASA and the former Soviet Union started sending people to space back in the mid-20th Century. Not only does that trip affect an astronaut’s outlook (just look what it did to William Shatner) but it changes their body. Space physicians continually study astronauts to understand just what happens to them in space. Their latest target? Astronaut brains.

NASA Astronaut and Cosmonauts Land Safely Together in Kazakhstan

After much speculation and concern the past month whether Russia would allow a US astronaut to ride back to Earth in a Soyuz spacecraft, Mark Vande Hei and two cosmonauts landed safely in Kazakhstan on March 30.

Mostly lost amid the political tensions due to Russia’s invasion of Ukraine, Vande Hei quietly set a record for the longest single spaceflight by an American, at 355 days. Vande Hei eclipsed astronaut Scott Kelly’s seemingly more heralded long-duration mission on the International Space Station in 2015, when he and Cosmonaut Mikhail Kornienko spent 340 days in space. Cosmonaut Pyotr Dubrov also spent 355 days on his first spaceflight, along with Vande Hei.

Lasers Could Send Missions to Mars in Only 45 Days

NASA and China plan to mount crewed missions to Mars in the next decade. While this represents a tremendous leap in terms of space exploration, it also presents significant logistical and technological challenges. For starters, missions can only launch for Mars every 26 months when our two planets are at the closest points in their orbit to each other (during an “Opposition“). Using current technology, it would take six to nine months to transit from Earth to Mars.

Even with nuclear-thermal or nuclear-electric propulsion (NTP/NEP), a one-way transit could take 100 days to reach Mars. However, a team of researchers from Montreal’s McGill University assessed the potential of a laser-thermal propulsion system. According to their study, a spacecraft that relies on a novel propulsion system – where lasers are used to heat hydrogen fuel – could reduce transit times to Mars to just 45 days!

Space Flight Destroys Your Red Blood Cells

It’s really true: space wants to kill us. And this time, space is trying to kill us from the inside out.

A new study on astronauts living on board the International Space Station shows that while in space, the astronauts’ bodies destroyed 54 percent more red blood cells than they normally would on Earth. Even one year after their flight and back on Earth, the symptoms of “space anemia” persisted in the 14 astronauts tested.

What’s Next for Blue Origin After Today’s Successful Flight?

Early this morning, from their Launch Site One facility in West Texas, Blue Origin made history as it conducted the first crewed flight of its New Shepard launch vehicle. The crew consisted of four commercial astronauts: Blue Origin and Amazon founder Jeff Bezos, his brother Mark Bezos, aerospace pioneer Wally Funk, and 18-year old student from The Netherlands Oliver Daemon.

Since There’s no Up or Down in Space, How do our Brains Deal With This?

Astronauts and cosmonauts in space have reported spatial disorientation problems, where they find it hard to get a sense of direction, or distinguish between what might be considered “up” or “down.” This is called “Visual Reorientation Illusions” (VRIs) where the spacecraft floors, walls and ceiling surfaces can suddenly exchange subjective identities.

An extreme example of this came when one shuttle astronaut reported feeling like the room was rotating around him when he opened his eyes one morning. Other astronauts have reported briefly not knowing where they were during a spacewalk.
