Q&A: How 3D Printing Can Enable On-Demand Space Launches

Posted by in categories: 3D printing, government, satellites

But in recent years the government has signaled its intent to open up the sector to private players and last year passed a series of reforms designed to foster innovation and encourage new start ups. Earlier this month Prime Minister Narendra Modi also launched the Indian Space Association, an industry body designed to foster collaboration between public and private players.

One of the companies that has been quick to pounce on these new opportunities is Agnikul, which is being incubated at the Indian Institute of Technology Madras in Chennai. This February, the company successfully test fired its 3D-printed Agnilet rocket engine, just four years after its founding.

While other private space companies like Relativity Space and Rocket Lab also use 3D printing to build their rockets, Agnikul is the first to print an entire rocket engine as a single piece. IEEE Spectrum spoke to co-founder and chief operating officer Moin SPM to find out why the company thinks this gives them an edge in the burgeoning “launch on-demand” market for small satellites. The conversation has been edited for length and clarity.

When it launches in 2,022 the GOES-T satellite will watch over Earth and give us early warning of natural disasters. But preparing it is an epic task for Lockheed Martin.

NASA Once Again Chooses SpaceX For New Mission GOES-U

Posted by in categories: climatology, mapping, satellites

NASA Once Again Chooses SpaceX For New Mission GOES-U: GOES-U will provide advanced imagery and atmospheric measurements of Earth’s weather, oceans, and environment, as well as real–time mapping of total lightning activity and improved monitoring of solar activity and space weather.

These satellites will be used by NOAA to forecast potentially hazardous weather and regularly monitor the weather. The weather of a particular region can be seen through the GOES-R series of satellites.

On the website, it says, “The GOES-R Series provides advanced imagery and atmospheric measurements of Earth’s weather, oceans and environment, real-time mapping of total lightning activity, and improved monitoring of solar activity and space weather.”

SpaceX to launch Emirati imaging satellite

Posted by in category: satellites

DUBAI, U.A.E. — SpaceX has won a contract to launch an Emirati high-resolution imaging satellite on a Falcon 9 rideshare mission in 2023.

The Mohammed Bin Rashid Space Centre (MBRSC) announced at an Oct. 27 press conference here, held during the 72nd International Astronautical Congress, that it selected SpaceX to launch its MBZ SAT satellite in the second half 2023. The center did not disclose the value of the contract.

Salem AlMarri, deputy director general of MBRSC, said the center looked at several launch providers for the mission. “At the end of the day, we look, for each mission, what is best. For this mission, SpaceX was the best.”

This device could usher in GPS-free navigation

Posted by in categories: particle physics, quantum physics, satellites

Don’t let the titanium metal walls or the sapphire windows fool you. It’s what’s on the inside of this small, curious device that could someday kick off a new era of navigation.

For over a year, the avocado-sized vacuum chamber has contained a cloud of atoms at the right conditions for precise navigational measurements. It is the first device that is small, energy-efficient and reliable enough to potentially move quantum sensors—sensors that use quantum mechanics to outperform conventional technologies—from the lab into commercial use, said Sandia National Laboratories scientist Peter Schwindt.

Sandia developed the chamber as a core technology for future that don’t rely on GPS satellites, he said. It was described earlier this year in the journal AVS Quantum Science.

South Korea fails to put satellite into orbit on domestic rocket

Posted by in category: satellites

GOHEUNG, South Korea — South Korea failed to deliver a satellite into orbit on Thursday, crushing its dream to become the 10th country in the world to reach the milestone using its own technology.

President Moon Jae-in said that the three-stage Nuri rocket could not reach orbit, although it flew as high as 700 km into space after all its three stages separated successfully.

“I am sorry that we could not reach the goal completely, but it’s still a very excellent accomplishment,” Moon said after the launch at the Naro Space Center on South Korea’s southernmost island of Oenarodo. “We have an uncompleted mission to deliver a dummy satellite into orbit safely.”

Chinese scientists build weapon that can cause satellites to explode

Researchers who built the device say it can lock itself onto the thruster nozzles used by most satellites and stay there for long periods undetected.

NASA’s ‘Armageddon’-style asteroid deflection mission takes off in November

Posted by in categories: asteroid/comet impacts, existential risks, satellites

NASA has a launch date for that most Hollywood of missions, the Double Asteroid Redirection Test, which is basically a dry run of the movie “Armageddon.” Unlike the film, this will not involve nukes, oil rigs or Aerosmith, but instead is a practical test of our ability to change the trajectory of an asteroid in a significant and predictable way.

The DART mission, managed by the Planetary Defense Coordination Office (!), involves sending a pair of satellites out to a relatively nearby pair of asteroids, known as the Didymos binary. It’s one large-ish asteroid, approximately 780 meters across — that’s Didymos proper — and a 160-meter “moonlet” in its orbit.

Adapter structure with 10 CubeSats installed on top of Artemis moon rocket

Posted by in categories: habitats, satellites

Workers at NASA’s Kennedy Space Center have lifted the Orion Stage Adapter on top of the Space Launch System moon rocket, adding the structure housing 10 CubeSat rideshare payloads heading into deep space on the Artemis 1 mission. But three of the CubeSat missions missed their opportunity to fly on the first SLS mission.

Teams inside the Vehicle Assembly Building at Kennedy raised the Orion Stage Adapter on top of the Space Launch System rocket Friday evening, according to Madison Tuttle, a NASA spokesperson.

The mounting of the circular adapter structure is one of the final steps in stacking the SLS rocket inside High Bay 3 of the iconic assembly building. The Orion spacecraft, NASA’s human-rated moon ship, will be added to the rocket in the coming days to complete the build-up of the 322-foot-tall (98-meter) launch vehicle for an unpiloted test flight to lunar orbit and back to Earth.

Waiting To Unload: Global Supply Chain Disruption Visible From NASA Satellites

Posted by in categories: biotech/medical, satellites

The pandemic has disrupted global supply chains and markets in ways that have led to backlogs of cargo ships at key ports.

Booming demand for consumer and goods, labor shortages, bad weather, and an array of COVID-related supply chain snarls are contributing to backlogs of cargo ships at ports around the world.

Among those seaports are the Port of Los Angeles and Port of Long Beach in Southern California, the two busiest container ports in the United States. On October 10 2021, the Operational Land Imager (OLI) on Landsat 8 captured this natural-color image of dozens of cargo ships waiting offshore for their turn to unload goods. On the same day, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA.
