AMSAT AO-7 to Have a good time fiftieth Anniversary
It has usually been reported that the oldest satellites nonetheless working in area are the area probes Voyager 1 and Voyager 2. The Voyagers have been each launched in 1977 to reap the benefits of the planetary alignment referred to as, again then, the “Grand Tour”. Their pictures modified the human imaginative and prescient of our photo voltaic system.
However, are they actually the oldest, nonetheless practical spacecraft in outer area? What if we embrace spacecraft that remained behind in Earth Orbit? Is it even plausible that the oldest nonetheless working satellite tv for pc in area wasn’t even designed or operated by NASA, USAF, ESA or some other area company? What if this satellite tv for pc was designed by Radio Amateurs and the ultimate meeting occurred in a basement laboratory not removed from Goddard House Flight Heart?
Then all issues thought-about, AO-7, a SmallSat launched on November 15, 1974 is the oldest working satellite tv for pc and remains to be offering service to tons of of Novice Radio operators all over the world. In its first life, AO-7 lived a really wholesome lifetime of 6.5 years. To not over-state the case, AO-7 outlived each its industrial and authorities co-passengers launched by Delta-104.
In late 1980, AO-7’s poor, abused, NiCad battery started to indicate severe indicators of elevated collection resistance. This was a certain signal to AMSAT command stations that the tip was in sight. The cells had been initially matched for capability by NASA. And, certainly the cells all failed inside a matter of weeks of each other.
AO-7 stayed asleep for 21 years, to the closest month. Then someday AO-7 awoke once more. This was solely attainable if one thing triggered an open circuit within the battery.
A really lively person of AO-7, Pat Gowain, G3IOR, from the UK, made a phone name to Perry Klein, W3PK, (first AMSAT President and designer of the VHF/HF transponder). This was on June 21, 2002. Pat puzzled if we had launched a brand new LEO spacecraft? He was listening to Morse Code Telemetry once more on the outdated beacon frequency of AO-7. He performed Perry a tape recording. It certain appeared like AO-7 telemetry!
Many radio amateurs who have been satellite tv for pc lovers in a short time started to look at the indicators from AO-7 and the second lifetime of the “Sleeping Magnificence” of satellites started.
Over the subsequent three weeks in November AMSAT Information Service will honor this historic achievement with a collection of quick articles highlighting the lifetime of AMSAT OSCAR 7. Within the meantime you should definitely go to a particular web page on the AMSAT web site the place you’ll find a set of AO-7 articles and hyperlinks at https://www.amsat.org/amsat-ao-7-a-fifty-year-anniversary/.

Again to Fundamentals: What’s the CubeSat Launch Initiative?
(Editor’s observe: On this avocation, we typically toss round acronyms or titles with scant understanding of what they stand for. Infrequently, ANS will supply quick articles that may assist up higher perceive the vocabulary of beginner satellites.)
The CubeSat Launch Initiative, or CSLI, is a NASA initiative that gives alternatives for certified CubeSats to fly as auxiliary payloads on future launches which have extra capability or as deployments from the Worldwide House Station (ISS). In quite simple phrases that signifies that NASA will cowl the price of offering a CubeSat a journey to area in trade for a report on the outcomes of that CubeSat’s investigation.
NASA’s CubeSat Launch Initiative offers alternatives for CubeSats constructed by U.S. academic establishments, and non-profit organizations, together with casual academic establishments reminiscent of museums and science facilities to fly on upcoming launches. By revolutionary know-how partnerships NASA offers these CubeSat builders a low value pathway to conduct scientific investigations and know-how demonstrations in area, thus enabling college students, lecturers, and college to acquire hands-on flight {hardware} design, growth, and construct expertise.
CSLI offers a low-cost platform for NASA science missions, together with planetary exploration, Earth remark, and basic Earth and area science. These efforts are a cornerstone within the growth of cutting-edge NASA enabling applied sciences together with laser communications, subsequent technology avionics approaches, energy technology, distributive sensor methods, satellite-to-satellite communications, and autonomous motion. Leveraging these missions for collaboration optimizes NASA’s know-how investments, fosters open innovation, and facilitates know-how infusion. CubeSat missions are enabling the acceleration of flight-qualified know-how help in elevating Expertise Readiness Ranges, which aligns to NASA’s goal of advancing the Nation’s capabilities by maturing cross-cutting revolutionary area applied sciences.
About half of all CSLI missions are conducting scientific investigations, most incessantly House Climate and Earth Science. Particular science investigation areas embrace: organic science, examine of close to Earth objects, local weather change, snow/ice protection, orbital particles, planetary science, space-based astronomy, and heliophysics. Sixty-six p.c of all CSLI missions are conducting know-how growth or demonstrations. Communications, propulsion, navigation and management, and radiation testing lead the subjects on this space. Different notable applied sciences are photo voltaic sails, additive manufacturing, femtosatellites, and sensible cellphone satellites. The low value of growth for a CubeSat permits for conducting larger threat actions that might not be attainable on large-scale NASA missions.
What’s the distinction between CSLI and ELaNa?
NASA’s Launch Providers Program manifests CSLI payloads with quite a lot of launch suppliers. Every launch with manifested CSLI payloads known as an ELaNa mission (Academic Launch of Nanosatellites) and is given an ELaNa mission quantity (e.g., ELaNa 49, ELaNa 50). Merely put, CSLI is the payload and ELaNa is the journey.
To be eligible for CSLI, a CubeSat investigation have to be of clear profit to NASA by supporting no less than one purpose or goal acknowledged within the NASA Strategic Plan. This plan may be discovered on NASA’s Site http://www.nasa.gov.

Voyager 1 Resorts to Transmitter that Hasn’t Been Used Since 1981
Following latest communication points, NASA’s Voyager 1 spacecraft resorted to utilizing a backup radio transmitter that has been inactive since 1981.
The interstellar explorer skilled a short pause in communications after placing itself in a protecting state to preserve energy. This was triggered by a command despatched on Oct. 16 instructing the spacecraft to activate one in every of its heaters.
The mission’s flight crew first realized there was a problem with Voyager 1 on Oct. 18, when the spacecraft failed to reply to that command. The crew later found that the spacecraft had turned off its major X-band radio transmitter and as an alternative converted to its secondary S-band radio transmitter, which makes use of much less energy, based on an announcement from NASA. The transmitter shut-off appears to have been prompted by the spacecraft’s fault safety system, which autonomously responds to onboard points.
The spacecraft’s fault safety system switched to the S-band radio transmitter, which, previous to that date, hadn’t been used since 1981. Given the spacecraft is situated a lot farther away in interstellar area at the moment than it was 43 years in the past, the flight crew was undecided a sign on the S-band frequency may very well be detected — particularly as a result of it transmits a considerably fainter sign whereas utilizing much less energy.
A command was despatched to the S-band transmitter on Oct. 22. Two days later, on Oct. 24, the crew was lastly in a position to reconnect with Voyager 1.
Voyager 1, which launched in 1977. Its time in deep area has taken a toll on its devices and triggered an rising variety of technical points. Earlier this yr, the crew needed to repair a separate communications glitch that was inflicting the spacecraft to transmit gibberish. Learn the whole story at https://tinyurl.com/ANS-308-Voyager.

- As thousands and thousands of individuals all over the world have fun Diwali, the Hindu pageant of lights, NASA astronaut Sunita Williams radioed residence a message of festive cheer. “I wish to prolong my warmest needs for a Glad Diwali to everybody celebrating the pageant of lights at the moment on the White Home and all over the world,” Williams mentioned in a latest video message despatched from the Worldwide House Station. Talking from the ISS’ window-filled cupola with Earth as her backdrop, Williams, who’s an American with Indian heritage, spoke about her father’s efforts to maintain Indian tradition alive after he migrated to the USA in 1957. She additionally touched upon the symbolism of Diwali — the triumph of fine over evil, mild over darkness and hope over despair. “Diwali is a time of pleasure as goodness on this planet prevails,” she mentioned.

- In just a few years, as a part of the Artemis Program, NASA will start the creation of everlasting infrastructure that may enable for normal missions to the floor (every year) and a sustained program of lunar exploration and growth. In a latest NASA-supported examine, a crew of researchers on the College of Illinois Urbana-Champaign investigated a brand new methodology of sending spacecraft to the Moon. It is called “multimode propulsion,” a way that integrates a high-thrust chemical mode and a low-thrust electrical mode – whereas utilizing the identical propellant. To interrupt it down, a multimode thruster depends on a single chemical monopropellant – like hydrazine or Superior Spacecraft Energetic Non-Poisonous (ASCENT) propellant – to energy chemical thrusters and an electrospray thruster (aka. colloid thruster). The latter aspect depends on a course of generally known as electrospray ionization (ESI), the place charged liquid droplets are produced and accelerated by a static electrical subject. Electrospray thrusters have been first utilized in area aboard the ESA’s LISA Pathfinder mission to exhibit disturbance discount. By growing a system that may swap as wanted, satellites will be capable to carry out propulsive manuevers utilizing much less propellant, thus requiring fewer gas transfers.

- Has orbital particles gone uncontrolled? In 1978, NASA scientists Donald J. Kessler and Burton G. Cour-Palais proposed a state of affairs the place the density of objects in Low Earth Orbit (LEO) could be excessive sufficient that collisions between objects would trigger a cascade impact. In brief, these collisions would create particles that might lead to extra collisions, extra particles, and so forth. This got here to be generally known as the Kessler Syndrome, one thing astronomers, scientists, and area environmentalists have feared for a lot of a long time. In recent times, and with the deployment of extra satellites than ever, the warning indicators have turn into simple. Presently, there’s an estimated 13,000 metric tons (14,330 US tons) of “area junk” in LEO. With the breakup and one other satellite tv for pc in orbit – the Intelsat 33e satellite tv for pc – the state of affairs will solely worsen.
