Everyone knows that solar energy is free and almost limitless here on Earth. The same is true for spacecraft operating in the inner Solar System. But in space, the Sun can do more than provide electrical energy; it also emits an unending stream of solar wind.
Solar sails can harness that wind and provide propulsion for spacecraft. NASA is about to test a new solar sail design that can make solar sails even more effective.

Fire on a spacecraft can be catastrophic. It can spread quickly in a confined space, and for trapped astronauts, there may be no escape. It’s fading in time now, but Apollo 1, which was to be the first crewed Apollo mission, never got off the ground because of a fire that killed the crew. There’ve been other dangerous spacecraft fires too, like the one onboard the Russian Mir space station in 1997.
In an effort to understand how fire behaves in spacecraft, NASA began its Saffire (Spacecraft Fire Safety Experiment) in 2016. Saffire was an eight-year, six-mission effort to study how fire behaves in space. The final Saffire test was completed on January 9th.

Although the U.S. Space Force is tasked with military operations in regards to space, they’ve never actually sent one of their own into orbit. This week, the agency announced that Col. Nick Hague will launch to the International Space Station in August 2024 to pilot the Crew-9 mission, as part of SpaceX’s ninth crew rotation to the ISS for NASA. He’ll join two NASA astronauts and a cosmonaut on the trip to space and then work as a flight engineer, spending six months on the station doing research and operations activities.

It’s a long way to the nearest star, which means conventional rockets won’t get us there. The fuel requirements would make our ship prohibitively heavy. So an alternative is to travel light. Literally. Rather than carrying your fuel with you, simply attach your tiny starship to a large reflective sail, and shine a powerful laser at it. The impulse of photons would push the starship to a fraction of light speed. Riding a beam of light, a lightsail mission could reach Proxima Centauri in a couple of decades. But while the idea is simple, the engineering challenges are significant, because, across decades and light-years, even the smallest problem can be difficult to solve.

Despite popular opinion, the first animals in space were not dogs or chimps, they were fruit flies launched by the United States in February 1947. The Soviet Union launched Laika, the first dog into space in November 1957 and now, it seems Iran is getting in on the act. A 500kg capsule known as the “indigenous bio-capsule” with life support capability was recently launched atop the Iranian “Salman” rocket. It has been reported by some agencies that there were animals on board but no official statement has been released.

A recent study published in Frontiers in Physiology examines how vibrating wearable devices, known as vibrotactors, can be used to help astronauts cope with spatial disorientation when in space, which results from the lack of gravitational cues, or natural sensory perceptions, they are accustomed to using when on Earth and despite the rigorous training the astronauts undergo to combat the symptoms of spatial disorientation. This study was conducted by a team of researchers at Brandeis University and holds the potential to help develop more efficient methods to combat spatial disorientation, especially with long-term missions to the Moon, and even Mars.

Although humans have flown to space for decades, the missions have primarily been in low-Earth orbit, with just a handful of journeys to the Moon. Future missions with the upcoming Artemis program aim to have humans living and working on the Moon, with the hopes of one day sending humans to Mars.
However, the environments of the Moon and deep space present additional health challenges to astronauts over low-Earth orbit (LEO), such as higher radiation, long-term exposure to reduced gravity and additional acceleration and deceleration forces. A new paper looks at the future of biomedicine in space, with a sobering takeaway: We currently don’t know enough about the biomedical challenges of exploring deep space to have an adequate plan to ensure astronaut health and safety for the Artemis program.

Engineers working with the European Space Agency have developed a new thruster design smaller than the tip of your finger. Despite its small size, this mini-thruster designed for CubeSats appears to be highly efficient without the use of toxic chemicals.

SpaceX Crew-7, the next group of four astronauts, are now on board the International Space Station, and this diverse crew is definitely putting “International” in the ISS. The new crew hails from four different countries: the US, Denmark, Japan and Russia. There will be 11 people on board the station for a few days before the Crew-6 foursome head back to Earth.
NASA has at least 200 science experiments and technology demonstrations queued up for Crew-7[‘s six months space, many of which will help prepare for the upcoming Artemis missions.

Virgin Galactic sent its first privately funded adventurers — and its first space sweepstakes winners — past the 50-mile space boundary today.
The tourists on the suborbital space trip known as Galactic 02 included Keisha Schahaff, who won two tickets in an online contest organized by the Omaze charity sweepstakes platform and a nonprofit group called Space for Humanity in 2021. She and her daughter, Anastatia Mayers, became the first mother-and-daughter duo to share a spaceflight, and the first spacefliers from the Caribbean island nation of Antigua and Barbuda.
“I kind of feel like I was born in this life for this,” Schahaff, a wellness coach, told NBC’s “Today” show. Her daughter is a college student who aims to become an astrobiologist.
Jon Goodwin — an 80-year-old British adventurer who competed as a canoeist in the 1972 Olympics — also broke barriers on today’s Galactic 02 flight. In 2005, he was one of the first customers to reserve a spot with Virgin Galactic, back when the price was $200,000. Then, almost a decade ago, he was diagnosed with Parkinson’s disease. Today he became only the second person with Parkinson’s to take a space trip. (The first was NASA shuttle astronaut Rich Clifford.)
