How to grow plants in a spacecraft
..., or PTH, but it requires regular injections and has a very short shelf life, which is problematic for long spaceflights. Therefore, a transgenic lettuce that produces PTH was engineered. Designing plants able to grow in space and be of use...

Beyond Earth’s magnetic field
...now be added, since it has been studied so little to date. In addition, hypomagnetic conditions may increase the impact of spaceflight factors and create additional risks to the health of space exploration crews in the future. Hypomagnetic fields are...

Are we asking the right questions about space debris?
... LEO as the collisions will be the most consequential and the collision rate is significant. Assurance of immediate spaceflight safety as the primary objective has encouraged us to examine the possible short-term, highly consequential events (rather...
