The robotic explorer Maven successfully slipped into orbit around Mars late Sunday night. Now the real work begins for the $671 million mission, the first dedicated to studying the Martian upper atmosphere and the latest step in NASA's bid to send astronauts to Mars in the 2030s. Researchers hope to learn where all the red planet's water went, along with the carbon dioxide that once comprised an atmosphere thick enough to hold moist clouds.
A SpaceX cargo ship rocketed toward the International Space Station on Sunday, carrying more than 5,000 pounds of supplies, including the first 3-D printer for astronauts in orbit. The printer, developed by Made in Space, is sturdier than Earthly models and is a technology demonstrator. . But NASA envisions astronauts one day using one to crank out spare parts as needed.
For future astronauts, the process of suiting up may go something like this: Instead of climbing into a conventional, bulky, gas-pressurized suit, an astronaut may don a lightweight, stretchy garment, lined with tiny, muscle-like coils. She would then plug in to a spacecraft’s power supply, triggering the coils to contract and essentially shrink-wrap the garment around her body.
Mars, get ready for another visitor or two. This weekend, NASA's Maven spacecraft will reach the red planet following a 10-month journey spanning 442 million miles (711 million km). If all goes well, the robotic explorer will hit the brakes and slip into Martian orbit Sunday night.
Groundbreaking contracts worth $6.8 billion were issued Tuesday to Boeing and SpaceX to transport U.S. crews to and from the space station using their CST-100 and Crew Dragon spacecraft, respectively. NASA’s awards to United States spacecraft will meet a goal of ending the nation’s sole reliance on Russia in 2017.
On Monday, NASA's inspector general released a report blasting the agency’s Near Earth Objects program, which is meant to hunt and catalog comets, asteroids and relatively large fragments of these objects that pass within 28 million miles of Earth. The purpose is to protect the planet against their potential dangers, but only 10% of the near-Earth objects bigger than 460 ft across have been catalogued, well short of the goal of 90% by 2020.
Workers at Kennedy Space Center gathered to watch as the Orion capsule, NASA's new spacecraft for humans, emerged from its assembly hangar Thursday morning, less than three months from its first test flight. During its Dec. 4 test flight, the capsule, unmanned, will shoot more than 3,600 miles into space and take two laps around Earth before re-entering the atmosphere at 20,000 mph and parachuting into the Pacific off the San Diego coast.
Objects in space tend to spin—and spin in a way that’s totally different from the way they spin on earth. Understanding how objects are spinning, where their centers of mass are, and how their mass is distributed is crucial to any number of actual or potential space missions, from cleaning up debris in the geosynchronous orbit favored by communications satellites to landing a demolition crew on a comet.
Yale Univ. astronomers have discovered a window into the early, violent formation of the cores of the universe’s monster galaxies, obscured behind walls of dust. After years of searching, scientists have observed one such turbulent, starbursting galactic core in the young universe using the NASA/ESA Hubble Space Telescope and a telescope from the W.M. Keck Observatory in Hawaii.
Astronomers using the Green Bank Telescope have discovered that filaments of star-forming gas near the Orion Nebula may be brimming with pebble-size particles: planetary building blocks 100 to 1,000 times larger than the dust grains typically found around protostars. If confirmed, these dense ribbons of rocky material may well represent a new, mid-size class of interstellar particles that could help jump-start planet formation.
Using a calculation originally proposed seven years ago to be performed on a petaflop computer, Lawrence Livermore National Laboratory researchers computed conditions that simulate the birth of the universe. When the universe was less than one microsecond old and more than one trillion degrees, it transformed from a plasma of quarks and gluons into bound states of quarks.
The moon appears to be a tranquil place, but modeling done by Univ. of New Hampshire and NASA scientists suggests that, over the eons, periodic storms of solar energetic particles may have significantly altered the properties of the soil in the moon’s coldest craters through the process of sparking—a finding that could change our understanding of the evolution of planetary surfaces in the solar system.
Three major experiments aimed at detecting elusive dark matter particles believed to make up most of the matter in the universe have gotten a financial shot in the arm. Two of the projects are at large national laboratories; the other is at the Univ. of Washington (UW). The selection will bring greater intensity to the UW research, with more equipment and scientists involved in the work.
The first analysis of space dust collected by a special collector onboard NASA’s Stardust mission and sent back to Earth for study in 2006 suggests the tiny specks, which likely originated from beyond our solar system, are more complex in composition and structure than previously imagined. The analysis opens a door to studying the origins of the solar system and possibly the origin of life itself.
Since 2006, when NASA’s Stardust spacecraft delivered its aerogel and aluminum foil dust collectors back to Earth, a team of scientists has combed through them. They now report finding seven dust motes that probably came from outside our solar system, perhaps created in a supernova explosion and altered by eons of exposure to the extremes of space. They would be the first confirmed samples of contemporary interstellar dust.
A commercial cargo ship has ended its monthlong space station visit. Astronauts aboard the International Space Station released the Cygnus supply ship, now full of trash for disposal early Friday. They parted company 260 miles above Africa's southwest coast. Orbital Sciences Corp. launched the Cygnus from Virginia in mid-July under a NASA contract.
A Purdue Univ. student team has designed, built and tested a critical part of a new a rocket engine as part of a NASA project to develop spacecraft technologies needed to land on the moon, Mars and other cosmic venues. The students are making a central part of the new engine—called the thrust chamber or combustor—as part of NASA's Project Morpheus.
Scientists hunting for life beyond Earth have discovered more than 1,800 planets outside our solar system, or exoplanets, in recent years, but so far, no one has been able to confirm an exomoon. Now, physicists from The Univ. of Texas at Arlington believe following a trail of radio wave emissions may lead them to that discovery.
The universe’s oldest, brightest beacons may have gorged themselves in the dense, cold, gas flows of the early cosmos—creating a kind of energy drink for infant black holes in the young universe—according to new research by scientists at Yale Univ. and the Weizmann Institute in Israel.
Turning what seemed like a science fiction tale into reality, an unmanned probe swung alongside a comet on Wednesday after a 4-billion mile chase through outer space over the course of a decade. Europe's Rosetta probe will orbit and study the giant lump of dust and ice as it hurtles toward the sun and, if all goes according to plan, drop a lander onto the comet in the coming months.
The world’s first commercial site for orbital rocket launches is to be built in the southernmost tip of Texas, east of Brownsville. SpaceX says it plans to launch 12 rockets a year from this site, investing $85 million and creating 300 jobs.
Laser technology originally developed at Los Alamos National Laboratory for the Mars Science Laboratory has been selected for NASA’s new Mars mission in 2020. The Curiosity rover is equipped with ChemCam, which allows researchers to sample rocks and other targets from a distance using a laser. The new “SuperCam” will offer this capability along with another spectrum for Raman and time-resolved fluorescence spectroscopy.
The million-mile-per-hour solar wind pushed out by the Sun inflates a giant bubble in the interstellar medium called the heliosphere, which envelops the Earth and the other planets. At the 40th International Committee on Space Research (COSPAR) Scientific Assembly in Moscow this week, scientists highlighted an impressive list of achievements in researching the outer heliosphere, which barely registered as a field of research ten years ago.
Taking fuel to Mars for return flights is heavy and expensive. The $1.9 billion Mars 2020 rover that NASA announced on Friday will include an experiment that will turn carbon dioxide in the Martian atmosphere into oxygen. It could then be used to make rocket fuel and for future astronauts to breathe. The device, named MOXIE, will make about three-quarters of an ounce of oxygen an hour.
At a press conference in Washington on Thursday, NASA announced the instruments to be designed into the Mars 2020 rover, a mission that will be based on the design of the highly successful Mars Science Laboratory rover, Curiosity, which landed almost two years ago. Managers made the selections out of 58 proposals received in January from researchers and engineers worldwide.
