NASA’s experimental X-59 jet, which could make supersonic commercial travel a reality, has been cleared for final assembly. The X-59 Quiet SuperSonic Technology (QueSST) aircraft, designed by Lockheed Martin, could take its first flight as soon as 2021.
With enough time, the technological challenges of sending humans to Mars and beyond are solvable. But psychologically, we’re not ready to leave our home.
In 1945 British science fiction writer Arthur C. Clarke—now best known for 2001: A Space Odyssey—correctly predicted the invention of satellites, the first of which launched into space in 1958. Then in 1963, Clarke predicted that a man would land on the moon and safely return to Earth sometime around the year 1970—which Neil Armstrong and Buzz Aldrin did in the summer of 1969. In 1973, Clarke predicted a future where humans would be able to monitor outer-space threats such as asteroids and other near-earth objects—NASA established its Near-Earth Object Observations Program in 1998.
Much of what Clarke suggested about our future in outer space, however, has slipped further and further behind schedule in recent years. For example, he predicted commercial space flights by the year 2011 and a manned mission to Mars by 2021. He also spoke of a manned mission to Jupiter by 2099, which experts say looks pretty unlikely at this point.
European Space Agency astronaut Alexander Gerst works on an experiment aboard the International Space Station looking into how cement reacts in space.
Concrete could provide humans in space with better protection from radiation and extreme temperatures than many other materials.
In the future, when humans live in and visit space, they’re going to need places to stay and work. That calls for durable infrastructure such as concrete. For the first time, astronauts made cement in space as part of a project looking into the effects of microgravity, NASA said last week.
The Deep Space Gateway, seen here in an artist’s rendering, would be a spaceport in lunar orbit. Boeing
As the 50th anniversary of the first Apollo landing approaches, a host of countries are undertaking lunar missions. What’s behind the new space race?
At 2.51am on Monday 15 July, engineers at India’s national spaceport at Sriharikota will blast their Chandrayaan-2 probe into orbit around the Earth. It will be the most ambitious space mission the nation has attempted. For several days, the four-tonne spacecraft will be manoeuvred above our planet before a final injection burn of its engines will send it hurtling towards its destination: the moon.
Exactly 50 years after the astronauts of Apollo 11 made their historic voyage to the Sea of Tranquillity, Chandrayaan-2 will repeat that journey – though on a slightly different trajectory. After the robot craft enters lunar orbit, it will gently drop a lander, named Vikram, on to the moon’s surface near its south pole. A robot rover, Pragyan, will then be dispatched and, for the next two weeks, trundle across the local terrain, analysing the chemical composition of soil and rocks.
The future of rocket manufacturing has touched down in Mississippi.
At NASA’s John C. Stennis Space Center, nestled in Hancock County, Miss., right on the border of Louisiana, the Los Angeles-based 3D-printed spacecraft manufacturer, Relativity Space, is planning a massive $59 million expansion to make a permanent manufacturing hub in this bucolic corner of the southeast.
One of the winning teams of a NASA competition to make a full-scale Mars habitat using
modeling software, Team SEArch+/Apis Cor, designed this Martian abode, which is built
from the upper part of a Hercules Single-Stage Reusable Vehicle.
The first humans on Mars will quickly become too fragile to have sex with.
That’s according to one scientist, who reckons colonists will warp into super-mutants who’ll keel over the moment they sleep with an Earthling.
NASA is keen to land humans on Mars in the 2030s with an eye on setting up a permanent Martian colony.
We Are Going There
NASA is confident it’s going back to the Moon — and this time, it plans to stay there.
On Tuesday, the agency released “We Are Going,” a new video narrated by Star Trek actor William Shatner.
In the clip, NASA details precisely how it plans to send a crewed mission to the Moon by 2024 — touching on everything from the development of brand-new spacecraft to the hunt for mission-supporting water beneath the Moon’s surface.
Some study participants will be spun in a short-arm human centrifuge that generates artificial gravity.
Like to lounge in bed? We might have your dream job.
NASA wants Earth-bound volunteers to test how artificial gravity might help keep astronauts healthy in space.
NASA and the European Space Agency will pay you $19,000 to lie in bed for two months. Two months! That’s a lot of Netflix.
The prolonged bed rest is part of a study that launched this week into the effects of weightlessness on the human body. Phase 2 will be conducted by the German Aerospace Center (DLR) from September through December in Cologne, Germany.
From bridges to cars, 3D printing proved this year that it’s still relevant and exciting.
The hype may have died down a little, but 3D printing was still creating waves in manufacturing in 2018. On the important-but-boring side, manufacturing companies are using the tech for things like weight reduction and cost savings. More interestingly, architects carried out a number of experiments that pushed the artistic limits of what 3D printing can do.
Here are some of the standout achievements and creations from 2018:
From a quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study published in the journal Nature Climate Change on April 25.
An international team of 32 authors from 24 institutions in eight countries led the effort, which involved using satellite data from NASA’s Moderate Resolution Imaging Spectrometer and the National Oceanic and Atmospheric Administration’s Advanced Very High Resolution Radiometer instruments to help determine the leaf area index, or amount of leaf cover, over the planet’s vegetated regions. The greening represents an increase in leaves on plants and trees equivalent in area to two times the continental United States.
They’ve awarded cash prizes as part of an ongoing competition.
NASA has selected five winners in an ongoing contest it has been running to get smart ideas about how to build a 3d-printed habitat on Mars.
The winners have passed level one of the 3D-Printed Habitat Centennial Challenge, which required developing about 60 percent of the design. Level Two will require greater complexity with 100 percent completion and an understanding of the hydraulics of each build. The teams will then create virtual structures and, on April 29, build them for real on the campus of Bradley University in Peoria, Ill.
The teams have different approaches and their video entries reflect that. First-place Team Zopherus, for example, highlights the autonomous robots that build out their modular structures. Using the Martian soil, their robots would build structures from the ground up.
Can gardens help astronauts go farther?
“Our plants aren’t looking too good,” astronaut Scott Kelly tweeted from the International Space Station on December 27, 2015. He was right: The attached picture showed four baby zinnias bathed in magenta light. Three of the four leafy stalks were discolored and curling in on themselves. The station’s garden was struggling to recover from a mold problem. It’s an issue familiar to terrestrial gardeners. And while on Earth, the problem means a trip to the local nursery for replacements, in space you can’t do that.
