  • Artemis II: NASA targets April 1 for the launch

    Further to a Flight Readiness Review (FRR) that took place this week, NASA held a press conference today to highlight the progress made toward the Artemis II crewed test flight around the Moon. Work is continuing on the SLS rocket and Orion spacecraft in NASA Kennedy’s Vehicle Assembly Building (VAB) after a helium flow issue was encountered in February. In addition to addressing this issue, technicians also installed new batteries and retested the flight termination system and avionics and control systems. The mission management team was satisfied with the thorough discussions about risks and the overall results of the FRR and determined that they would try to launch as early as April 1, 2026, pending completion of all required work in the VAB and at the launch pad. The launch window opens at 6:24 pm ET.

  • Monitoring radiation for astronaut health

    Radiation is one of the key challenges faced by astronauts living and working beyond the protective shield of Earth’s atmosphere. As Canada and its international partners advance plans for missions to the Moon, and eventually Mars, the Canadian Space Agency (CSA) continues to invest in technology to better understand exposure levels. The CSA has awarded a contract of $5.5 million to Bubble Technology Industries for the continued development of the CANS, a compact and autonomous instrument designed to measure neutron radiation exposure in space.

  • Artemis II: NASA prepares to roll back rocket to assembly building, will not launch in March

    NASA will be rolling back the Artemis II SLS rocket and Orion spacecraft to the Vehicle Assembly Building (VAB) at the Kennedy Space Center in Florida observing interrupted flow of helium in the rocket’s interim cryogenic propulsion stage (ICPS). Weather pending, the roll back will take place on Tuesday, February 24. NASA is investigating potential faults, but accessing and remediating any of these issues can only be performed in the VAB. This removes the March launch opportunities from consideration.

QSOs with Stations in Israel, Palestine and Lebanon

2026-05-08 - Again for Israel, Palestine (Gaza and the West Bank) and Lebanon, Google AI reveals the following information.  Again keep in mind that radio transmissions can be subjected to direction-finding and the transmitting station could be targeted:

Amateur radio (ham radio) in the West Bank and Gaza operates under the E4 prefix, allocated to the Palestinian Authority. While activity is extremely rare and sporadic, particularly in Gaza due to the ongoing conflict and equipment restrictions, occasional DXpeditions (like E44OM and E44DX) provide active contacts from the region.

QSOs with Stations in Iran

2026-05-08 - Amateurs making contacts (QSOs) with stations in Iran should exercise caution due to ongoing hostilities between Iran, Israel and the United States.  Remember that their stations can be subjected to direction-finding and targeted.  So a contact, like for Ukraine, could place the Iranian station in real danger.  The following is what Google AI reveals (but strangely it does not urge caution and safety):

FCC Approves AST Space Mobile's License for Operations in 430–440 MHz

Details
Hits: 1095

IARU 2026-04-29 - On April 21st, 2026, the FCC granted AST Space Mobile permission to conduct emergency Telemetry, Tracking & Control (TT&C) operations outside the United States in the 430–440 MHz amateur radio band for all their planned 248 satellites. More than 2,500 comments were submitted by ARRL, AMSAT, other IARU societies and individual radio operators during the FCC review period. The license allows emergency operations when no other bands are available for up to 24 hours on the center frequencies of 430.5 MHz, 432.3 MHz, 434.1 MHz, 435.9 MHz, and 439.5 MHz (each with 50 kHz bandwidth), and was granted by the FCC pursuant to Article 4.4 of the ITU Radio Regulations.
