Hubble’s Dusty Surprise: Why Uranus’
Moons Are Darker on the “Wrong” Side (Source: SciTech Daily)
The four moons in this study — Ariel, Umbriel, Titania, and Oberon —
are tidally locked to Uranus, so that they always show the same side to
the planet. The side of the moon facing the direction of travel is
called the leading hemisphere, while the side that faces backward is
called the trailing hemisphere. The thinking was that charged particles
trapped along the magnetic field lines primarily hit each moon’s
trailing side, which would darken that hemisphere.
Researchers suspect that Uranus’ magnetosphere may be fairly quiescent,
or it may be more complicated than previously thought. Perhaps
interactions between Uranus’ moons and magnetosphere are happening, but
for some reason, they’re not causing asymmetry in the leading and
trailing hemispheres as researchers suspected. The answer will require
further investigation into enigmatic Uranus, its magnetosphere, and its
moons. (6/15)
Congress Wants New NASA Nominee ASAP
(Source: Space News)
Members of Congress are asking the White House to swiftly select a new
nominee for NASA administrator. In briefings at the Paris Air Show
Monday, House and Senate members said they were surprised that the
White House withdrew the nomination of Jared Isaacman to lead NASA.
They said it was important to get a new person nominated, and then
confirmed by the Senate, to provide long-term leadership for NASA. They
also expressed some concerns about the proposed NASA budget that would
cut agency funding by about 25%. Rep. Brian Babin (R-TX), chairman of
the House Science Committee, said he backed a proposal by Sen. Ted Cruz
(R-TX) to add $10 billion to a budget reconciliation bill for NASA
human spaceflight programs. (6/16)
Ursa Major to Provide Engines for
Stratolaunch Tests (Source: Space News)
Ursa Major won a contract to provide engines for Stratolaunch's
hypersonic vehicles. Under the $32.9 million contract announced Monday,
Colorado-based Ursa Major will deliver an upgraded variant of its
Hadley engine for use in Stratolaunch's reusable hypersonic vehicle
called Talon-A. The contract covers 16 such engines. Hadley engines
have powered multiple Talon-A missions, and the upgraded version will
offer increased reusability. The engine produces 5,000 pounds-force of
thrust and operates on liquid oxygen and kerosene. (6/16)
ESA Approves Plan for Earth
Observation Satellite System (Source: Space News)
ESA is also moving ahead with a Earth observation satellite program
with security applications. The ESA Council formally approved an
"enabling resolution" last week instructing the agency to prepare a
proposal for the European Resilience from Space (ERS) program, which
will include high-resolution optical and radar satellites with revisit
times as short as 30 minutes. ESA member states will be asked to
contribute about one billion euros ($1.15 billion) to ERS at the
November ministerial as the first phase of the program. It will
eventually be a joint effort with the European Commission envisioned as
a "system of systems" that will include the IRIS² secure connectivity
constellation and a low Earth orbit navigation system that will give
European governments independent access to such capabilities for civil
and military applications. (6/16)
China Launches Science Satellite on
Long March 2D (Source: Space News)
China launched a scientific satellite Saturday. A Long March 2D rocket
lifted off at 3:56 a.m. Eastern from the Jiuquan Satellite Launch
Center, placing into orbit the China Seismo-Electromagnetic Satellite-2
(CSES-2), also known as Zhangheng-2. The satellite, the successor to
the CSES-1 spacecraft launched in 2018, will look for correlations
between earthquakes and electron flux activity in the inner Van Allen
belt, which could be used to predict seismic activity. The satellite
includes contributions from Italy and Austria. (6/16)
China's Cangyu Plans Data Relay
Constellation (Source: Space News)
A Chinese company is proposing to develop a data relay satellite
constellation. Cangyu Space Technology presented its plans at a Chinese
conference earlier this month. The constellation will consist of 13
satellites in different orbits: six in medium Earth orbit, four in
geostationary orbit and three in inclined geosynchronous orbits.
According to the company presentation, use cases appear to include data
relay for UAVs, launch vehicle telemetry, maritime and aviation assets
and potentially Internet of Things and data nodes in remote or rural
areas. The first satellite is in production for a launch by the end of
next year. (6/16)
White House "Reviewing" SpaceX
Contracts (Source: Reuters)
The White House is reportedly "reviewing" SpaceX contracts with the
U.S. government. According to sources, the White House asked NASA and
the Defense Department to provide it with details about its existing
contracts with the company, just after Elon Musk's acrimonious
departure from the Trump administration. It's unclear what the White
House was specifically reviewing and what steps it might take to cancel
or revise those contracts, steps that could impair operations by the
space agency and military. (6/16)
ICEYE Radar Imaging Added to SkyFi
Satellite Data Platform (Source: Space Daily)
SkyFi and ICEYE US have launched a strategic partnership to incorporate
ICEYE's synthetic aperture radar (SAR) data into the SkyFi Earth
observation platform. The agreement initiates a broader collaboration
aimed at expanding access to commercial radar imaging, with ICEYE
tasking and archive features set to appear soon in SkyFi's web and
mobile tools.
ICEYE operates the largest commercial SAR satellite constellation,
boasting more than 50 satellites. Its integration into SkyFi's
interface allows users to access radar imaging by simply defining an
area of interest and choosing between tasking or archived data. This
provides critical support for applications such as port monitoring,
infrastructure assessment, and coastal surveillance. (6/16)
NATO Partners with Planet Labs to
Boost global Surveillance and Early Warning Capability (Source:
Space Daily)
Planet Labs has secured a seven-figure agreement with NATO to deliver a
comprehensive daily monitoring and intelligence platform, reinforcing
the Alliance's ability to respond swiftly to global developments. The
contract comes amid heightened efforts by European nations to bolster
defense readiness in light of evolving geopolitical tensions.
Under this agreement, Planet will integrate its PlanetScope Broad Area
Monitoring technology with advanced artificial intelligence (AI) and
machine learning (ML) analytics. This combination aims to deliver
persistent space-based surveillance, early warning indicators, and
enhanced maritime domain awareness (MDA) to NATO decision-makers. (6/16)
Muon Space Secures $146 Million to
Scale Satellite Manufacturing and Defense Constellations
(Source: Space Daily)
Muon Space has finalized an $89.5 million Series B1 funding round,
bringing its total Series B raise to $146 million. The new capital mix
includes $44.5 million in equity and $45 million in credit facilities,
building on the initial Series B secured in August 2024.
The funding will accelerate Muon's scale-up strategy, expanding its
satellite production capacity, vertically integrating key systems such
as propulsion and infrared/radio frequency instruments, and enhancing
its automated constellation operations platform and global ground
station footprint. With a 50% workforce increase since December and
over $100 million in contracts signed in 2024, Muon's growth includes a
major deal with SNC to develop satellites for the Vindler commercial RF
sensing network. (6/16)
Elon Musk Eyes Launch Opportunities
from South Africa’s Western Cape (Source: Space in Africa)
Elon Musk has expressed strong interest in possibly launching SpaceX
rockets from South Africa’s Denel Overberg Test Range near Arniston, a
move that could strengthen the country’s emerging role in the global
space economy. Following a high-profile diplomatic exchange between
former President Donald Trump and South African officials, the proposal
was raised during a closed-door meeting at the White House.
According to individuals familiar with the discussions, Musk expressed
interest in two key areas relating to South Africa: access to the
Overberg site for orbital launches, and concerns about the availability
of rare-earth magnets amid tightening export restrictions from China.
