An investigation has pinpointed a space weather event or a micrometeroid strike as the most likely cause of the total failure of the Intelsat 29e communications satellite in April, Spaceflightnow reports.
“The failure review board concluded that the anomaly was either caused by a harness flaw in conjunction with an electrostatic discharge event related to solar weather activity, or the impact of a micrometeoroid,” Intelsat said in a discussion document released Tuesday in conjunction with the company’s second quarter financial numbers.
The board formed to investigate the Intelsat 29e failure included members from Boeing, which built the spacecraft, Intelsat and external independent experts.
Intelsat 29e was launched Jan. 27, 2016, aboard an Ariane 5 rocket from French Guiana for a planned 15-year mission. Based on the Boeing 702MP satellite design, Intelsat 29e was positioned in geostationary orbit at 50 degrees west longitude, where its thrusters kept the satellite parked over the same geographic region, with the spacecraft’s orbital velocity matching the rate of Earth’s rotation.
Intelsat reported the conclusions of the board when reporting its second quarter financial results.
“We recognized an impairment charge of $381.6 million during the three months ended June 30, 2019 relating to the failure of Intelsat 29e,” the company said in a press release.
“The impairment charge consisted of approximately $377.9 million related to the write-off of the carrying value of the satellite and associated deferred satellite performance incentive obligations,and approximately $3.7 million related to prepaid regulatory fees,” the statement added.
COLOGNE, Germany (DLR) — Digitalisation, climate change and technological disruption are shaping the future. This is where interdisciplinary research at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) proves valuable.
On 27 June 2019, the DLR Senate approved the founding of seven new institutes and facilities. The background to this was a resolution passed in the German Federal Parliament on 23 November 2018. By taking this step, DLR is strengthening Germany as a location for technological research and creating highly-skilled jobs.
GREENBELT, Md. (NASA PR) — Ready, SET, go — NASA’s Space Environment Testbeds, or SET, will launch in June 2019 on its mission to study how to better protect satellites in space. SET will get a ride to space on a U.S. Air Force Research Lab spacecraft aboard a SpaceX Falcon Heavy rocket from NASA’s Kennedy Space Center in Florida.
On Sept. 2, 1859, a powerful solar storm of highly charged particles overwhelmed the Earth’s protective magnetic field, shorting out telegraph wires and igniting fires across the United States and Europe.
Aware of the havoc that a similar event could cause on a planet increasingly dependent on satellites and electronics, the U.S. government is looking to better predict, protect against and recover from future solar storms.
President Donald Trump has issued an executive order aimed at protecting America’s critical infrastructure against electromagnetic pulses (EMPs) that could result from solar storms and nuclear explosions.
LONDON (UKSA PR) — New national space funding worth £7 million [$9.25 million] will ensure UK scientists play a leading role in a new space weather mission, the Science Minister Chris Skidmore announced on the first day of British Science Week (8 March).
The Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) mission will study how the solar wind interacts with the Earth’s magnetosphere, which can impact on satellites, power grids and communications networks integral to our modern lives.
PARIS, 1 March 2019 (ESA PR) — One of the most visible — and fabulously beautiful — effects of this ‘space weather’ on our planet are the aurora borealis, the famous ‘northern lights’ that dance across the high (and low) latitudes.
Throughout human history, spectacular auroral eruptions have given rise to fearful beliefs of mythological creatures, have driven folklore and have influenced culture, religion and art.
Last week, we took a look at the significant increase in NASA’s budget for FY 2019. In this story, we will examine the budget increases for the Commerce Department — which manages the nation’s weather satellites — and the Department of Transportation, which oversees commercial launches. We will also take a look how the White House’s National Space Council fared.
National Oceanic and Atmospheric Administration (NOAA)
NOAA’s satellite programs received $1,45 billion, which is an increase of $55 million over FY 2018. The bulk of the funding is designated for the GOES-R, Joint Polar Satellite System (JPSS) and Polar Follow-on (PFO) programs. The amounts include:
WASHINGTON (NASA PR) — NASA has selected a new mission that will help scientists understand and, ultimately, forecast the vast space weather system around our planet. Space weather is important because it can have profound impacts – affecting technology and astronauts in space, disrupting radio communications and, at its most severe, overwhelming power grids.
The new experiment will, for the first time, obtain global observations of an important driver of space weather in a dynamic region of Earth’s upper atmosphere that can cause interference with radio and GPS communications.
NASA has received a $21.5 billion budget for fiscal year 2019, which is $736.86 million above FY 2018 and $1.6 billion above the total requested by the Trump Administration.
The funding, which came more than four months into the fiscal year, was included in an appropriations bill signed by President Donald Trump on Friday. NASA’s budget has been on an upward trajectory over the last few years. In FY 2018, the space agency received an $1.64 billion increase over the previous year.
Five years ago, a group of UCLA undergrads came together with a common goal — to build a small satellite and launch it into space. In the years since, more than 250 students — many of whom are now UCLA graduate students and alumni — have been the mechanical engineers, software developers, thermal and power testers, electronics technicians, mission planners and fabricators of the twin Electron Losses and Fields Investigation CubeSats, known as ELFIN.
LOGAN, Utah — The head of NASA’s science programs unveiled an $100 million per year initiative on Monday focused on the use of small scuebce satellites that includes data buys from three spacecraft constellation operators.
Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate, said the funding would go to targeted space science, technology and educational projects. He made the announcement during a keynote address at the annual Small Satellite Conference in Logan, Utah.
A key element of the initiative is the purchase of Earth science data from companies with satellite constellations in Earth orbit. Zurbuchen announced that the first purchases will be made from DigitalGlobe, Planet and Spire. He did not disclose the amounts of the awards.
Zurbuchen said NASA’s goal is to work with the growing small-satellite industry, not to compete with it. The space agency will invest in early-stage research and development to advance and test new technologies.
Zurbuchen also announced a new opportunity for small-satellite technology demonstrations focused on heliophysics that will be funded at up to $65 million.
“This opportunity will ultimately help deploy #SmallSat technologies to better understand @NASASun science and protect Americans by protecting US technological infrastructure on Earth and in space from the perils of space weather,” he tweeted.
Zurbuchen said NASA plans to provide more launch and rideshare opportunities for small satellites built by government, commercial and international partners.
WASHINGTON (House Science Committee PR) – The House Science, Space, and Technology Committee approved legislation today to better protect lives, property, and infrastructure from the adverse effects of space weather.
ARLINGTON, Va. (DARPA PR) — Models for providing hourly terrestrial weather forecasts anywhere in the world have become increasingly precise—our smartphones buzz or chirp with local alerts of approaching thunderstorms, heavy snow, flash floods, and big events like tornados and hurricanes.
The military relies on accurate weather forecasts for planning complex operations in the air, on ground, and at sea. But when it comes to predicting environmental conditions in specific locations within the vast volume of space, no similar forecasting exists.
