03
What the reminder establishes
NASA Science announces that the 2027A IRTF observing-proposal call opened on September 1. Its reminder sets the submission deadline for Thursday, October 1, 2026, at 5:00 p.m. Hawaii Standard Time. [1]
The supplied page does not say how observing time will be allocated or provide the underlying call’s full application requirements. [1]
- Solicitation number: NN2027AOBSERV_IRTF.
- NASA Science identifies the opportunity as observing proposals for the NASA Infrared Telescope Facility, or IRTF.
- The agency describes 2027A as February 1 through July 31, 2027.
04
Remote-observing provision
NASA Science says remote observing is offered from locations with broadband internet access for projects using IRTF facility instruments. This confirms an access option, not broader applicant eligibility or technical readiness requirements. [1]
- Remote observing is described as available from any location with broadband internet access.
- NASA Science limits that statement to projects that use IRTF facility instruments.
- The reminder points readers to further computer and remote-observing information, but that linked material is not part of the verified packet.
05
What remains to verify
Interested researchers should rely on the linked full announcement and application form for the conditions needed to submit safely. In particular, the reminder alone does not establish who may apply, which instruments are available, what documents are required, or the proposal evaluation process. [1]
- The primary source is NASA Science’s reminder page: https://science.nasa.gov/astrophysics/programs/cosmic-origins/community/reminder-2027a-nasa-irtf-call-for-proposals
- The reminder refers readers to a full announcement, instrument information, remote-observing information, and an online application form.
- Those linked documents were not acquired, so this brief cannot verify their contents or give a verified direct application URL.
06
What interested applicants can do
NASA Science directs readers to review the full announcement and use its online application form, but those linked materials were not included in the verified evidence.
- 01
Confirm the deadline: October 1, 2026, at 5:00 p.m. Hawaii Standard Time.
- 02
Check the full announcement for available instruments, eligibility, proposal requirements, review criteria, costs, and required documents.
- 03
Confirm whether a proposed project uses an IRTF facility instrument and can meet the stated remote-observing conditions.
07
Limits of this edition
The reminder does not specify the year of the September 1 opening date, although it is labelled for semester 2027A and published in 2026.
The supplied evidence does not include the online application form or its direct participation link.
Available instruments, eligibility, proposal format, review criteria, costs, required documents, and allocation details are not provided in the acquired reminder.
The source gives Hawaii Standard Time but does not provide a UTC conversion or IANA time-zone identifier.
Remote observing is stated for projects using IRTF facility instruments; the reminder does not establish that it applies to every instrument or project type.

NASA Reports an Evolving 10-Sided Wave at Saturn’s South Pole
NASA says Hubble data reveal an evolving 10-sided wave in a jet stream around Saturn’s south pole, extending through multiple atmospheric layers. The agency reports that prior Hubble searches and Cassini observations did not show a long-lived southern counterpart, but the wave’s cause, lifespan and stability remain unresolved.
