SNAPSHOT: Human Spaceflight

From the early days of the space race, sending humans to space has always been a key priority. The International Space Station (ISS) has maintained a continuous human presence in orbit for more than 20 years, and microgravity research on space stations has provided valuable insight for future long-term human missions in space.

OSIRIS-REx Delivers Asteroid Sample After Seven Years in Space

NASA’s OSIRIS-REx spacecraft returned a sample from the asteroid Bennu, which could help scientists better understand the formation of the solar system. After more than a decade of planning and seven years of space flight traversing more than 1 billion miles, a sample from the asteroid Bennu safely landed on Earth.

As LEO Popularity Surges, Concern Escalates Over Debris Risk

Starting with Sputnik, humankind has littered low Earth orbit with clouds of debris, with as many as 170,000 objects ranging in size from poppy seeds to defunct satellites of school-bus size whizzing around the planet in uncontrolled orbits. With an historic surge in demand for satellites in low Earth orbit, including plans that could add more than 50,000 spacecraft, and planned space stations, the debris problem could grow exponentially.Starting with Sputnik, humankind has littered low Earth orbit with clouds of debris, with as many as 170,000 objects ranging in size from poppy seeds to defunct satellites of school-bus size whizzing around the planet in uncontrolled orbits.

Lessons from Earthbound Launchpad Failures Inform Future Missions to Moon, Mars

The incredible power in rocket boosters is magnificent when they are safely in the sky, but basic laws of physics are problematic closer to the ground, with every action creating an equal and concrete-shredding reaction. Now, with the Moon and Mars in NASA’s sights, engineers are working to overcome the dangers rocket thrust could bring when landing and taking off without the safety of a launchpad.The incredible power in rocket boosters is magnificent when they are safely in the sky, but basic laws of physics are problematic closer to the ground, with every action creating an equal and concrete-shredding reaction.
