PASADENA, Calif. (NASA/JPL-Caltech PR) — When the Orbiting Carbon Observatory 3, OCO-3, heads to the International Space Station, it will bring a new view — literally — to studies of Earth’s carbon cycle.
From its perch on the space station, OCO-3 will observe near-global measurements of carbon dioxide on land and sea, from just after sunrise to just before sunset. That makes it far more versatile and powerful than its predecessor, OCO-2.
KENNEDY SPACE CENTER, Fla. (CASIS PR) — Early Saturday morning at 2:48 a.m. EDT, a variety of payloads managed by the International SpaceStation (ISS) U.S. National Laboratory were successfully launched to the spacestation on SpaceX’s 17th commercial resupply services mission from the Cape Canaveral Air Force Station in Florida. Many of the ISS National Lab investigations included on this mission are aimed at improving human health on Earth, with several focused on drug development.

PARIS, 4 May 2019 — Wrinkles, muscle pain, high blood pressure and a clumsy brain are all natural consequences of getting old. As our cells rust over time, a key to fighting chronic disease may be in tiny, smartly designed particles that have the potential to become an anti-ageing supplement. A European experiment seeking innovative antioxidants is on its way to space.
Rocket Lab has completed the launch readiness review for Electron’s first night launch on Saturday. The launch window for the flight, which will carry three technology demonstration satellites for the U.S. Department of Defense, opens at 2:00 a.m. EDT (0600 UTC/ 18:00 NZT).
SpaceX scrubbed the launch of a Dragon supply ship to the International Space Station on Friday due to an electrical issue on the Of Course I Still Love You drone ship. There was also a helium leak involving the Falcon 9 booster.
The next launch opportunity is Saturday at 2:48 a.m. EDT (0648 UTC).
Specially Developed Experiment Modules Contain MIT Tissue Chips
GREENVILLE, Ind. (April 26, 2019) – An uncrewed SpaceX cargo resupply spacecraft scheduled to launch to the International Space Station May 1 will contain experiment modules specially-developed by Techshot Inc., for a Massachusetts Institute of Technology tissue chip experiment. Tissue chip devices are designed as accurate models of the structure and function of human tissues such as the lungs, liver, heart and bone.
HOUSTON (NASA PR) — Asteroid researchers on Earth will soon gain a powerful new way to remotely conduct experiments aboard the International Space Station. The device, called the Hermes Facility, is an experiment station that can communicate with scientists on the ground and give them the ability to control their studies almost as if they were in space themselves. Hermes will be carried to the space station aboard the SpaceX CRS-17 ferry flight.
Hermes is the creation of Dr. Kristen John, a researcher with the Astromaterials Research and Exploration Science (ARES) division at NASA’s Johnson Space Center (JSC). John and her research team developed Hermes as a way to study how samples of simulated asteroid particles behave in microgravity and the vacuum of space. (more…)
CAPE CANAVERAL, Fla. (NASA PR) — NASA commercial cargo provider SpaceX is targeting no earlier than 4:21 a.m. EDT Tuesday, April 30, for the launch of its next resupply mission to the International Space Station.

KENNEDY SPACE CENTER, Fla., April 22, 2019 (CASIS PR) – The International Space Station (ISS) U.S. National Laboratory is finalizing more than a dozen payloads for launch to the orbiting laboratory aboard SpaceX’s Dragon spacecraft. Many of these payloads are aimed at improving human health on Earth, with several focused on drug development and screening. Research concepts include commercial companies leveraging microgravity to improve drug delivery systems, other government agencies funding transformative science, and academic inquiry to enhance fundamental knowledge of diseases on Earth.
WASHINGTON (NASA PR) — NASA will provide coverage of the upcoming prelaunch and launch activities for the SpaceX Demo-1 flight test to the International Space Station for the agency’s Commercial Crew Program, which is working with the U.S. aerospace industry to launch astronauts on American rockets and spacecraft from American soil for the first time since 2011.
HOUSTON, January 31, 2019 (NanoRacks PR) — NanoRacks successfully completed the 15th CubeSat Deployment mission from the Company’s commercially developed platform on the International Space Station. Having released five CubeSats into low-Earth orbit, this mission marks NanoRacks’ 190th CubeSat released from the Space Station, and the 228th small satellite deployed by NanoRacks overall.
The CubeSats deployed were launched to the Space Station on the 16th contracted resupply mission for SpaceX from the Kennedy Space Center in December 2018.
NanoRacks offered an affordable launch opportunity, payload manifesting, full safety reviews with NASA, and managed on-orbit operations in order to provide an end-to-end solution that met all customer needs.
On SpaceX’s recent 16th commercial resupply mission, 40 mice of two different age groups were sent to the orbiting laboratory for comparison with age-matched ground controls as part of this reference mission. Awardees from this RFP will have the ability to evaluate spaceflight biospecimens once they are returned to Earth as well as ground controls.
Cape Canaveral, Fla. (NanoRacks PR) – Last weekend, Dragon, the spacecraft from the sixteenth SpaceX contracted resupply mission, berthed with the International Space Station carrying educational experiments, CubeSats, and industry science research from NanoRacks’ customers into orbit. Within this mission, the NanoRacks team delivered payloads for four of the Company’s commercial platforms on Space Station.
Wired has a fascinating story that details how SpaceX’s cargo Dragon spacecraft have been contaminating the International Space Station during their stays there – and how NASA has tried to hide the fact.
The contamination was discovered by the Stratospheric Aerosol and Gas Experiment (SAGE) III Earth observing instrument, which was launched to the station aboard SpaceX’s CRS-10 resupply mission in February 2017. The instrument has crystals in it capable of detecting contamination at the space station.
The results are preliminary, but Dragon may have deposited, according to this presentation, up to 21 times the allowed amount of contamination on one sensor. The crystals also significantly changed in frequency when the next Dragon docked, and the report estimates that this mission may have left behind up to 32 times the rule-abiding amount of extra matter on one sensor….
During this thirteenth mission, one sensor may have been sprayed with up to 73 times more than what’s allowed during a sojourn. And for the month or so that Dragon was docked at the Station, two of the sensors individually detected more contamination than is allowed—total, from everything on the Station—in a whole year.
Among the space assets at risk from the capsule’s outgassing is the U.S. Laboratory Science Window, a porthole through which astronauts and instruments can gaze out on Earth. On the more scientific side, there’s CATS, an instrument that measures smoke, pollution, dust, and other particles in the planet’s atmosphere. In total, seven sensitive areas or instruments on the ISS, including SAGE, could be contaminated beyond the limit.
“NASA has communicated with the Station payload community its findings, and payload developers have responded either that their instruments have experienced no impact or they have taken precautions to mitigate impacts to their science,” says Space Environments in a statement. The SAGE III team closes the instrument’s “contamination door,” as a standard operating procedure, when any spacecraft visit to protect its optical instrument, although the resulting measurements aren’t as sensitive .
SpaceX said it is working with suppliers to develop low outgassing materials for use in future Dragon spacecraft. It said NASA pre-approved the materials used in the resupply ships. (The story, however, says that it’s possible materials such as paint are not being applied and cured properly.)
The information came from a presentation marked unclassified and unlimited public distribution that was posted on the NASA Technical Reports Server in September. A day after the Wired writer requested an interview about it with NASA officials, the document disappeared from the server. A NASA official said the report is “under review” and told Wired to submit a Freedom of Information Act request for it.
