Share Your Team's Content on ESRA Social Media!

Jan. 22, 2023, 5:51 p.m. PST by ESRA Media

Want to share info on your team and promote ESRA and the Spaceport America Cup? Well now is your chance! 

As ESRA is strictly a volunteer force, it is difficult for us to create and post media on a regular basis. What we are looking to do is ask the teams for help. ESRA has a media service called Cloud Campaign and we can load it up with media post and set up schedules for when to post media. If you want to feature your team and promote the event, simply email us at the email below and send a picture(s) or a short video and once approved we will add it to the social media and start posting on a regular basis. 

What we need:

  • Email Subject: Team [###]: [Brief Description]
  • Media: Picture(s) or a video. Please attach in email, or send an easily sharable link. We have google drive accounts, but outside of that, we should not be requireed to set up an account.
  • Description & Twitter Description: Send us your text to go with the post and be sure to include appropriate hashtags. Twitter is the limit on text size at 280 characters. Anything more will not be posted to Twitter, but we will still post to our other platforms. If you are exceeding 280 characters, please include two versions of your text, a "Description" and "Twitter Description".
  • Social Tags: We need your tags for social media so we can tag you and send you more potential subscribers. These should be split up into the following accounts like the example below. Multiple tags per social are allowed. 
    • Facebook: @ESRA.Rocket, @spaceportamericacup
    • Instagram: @ESRA.Rocket, @spaceportamericacup
    • LinkedIn: @esra-rocket
    • Twitter: @SoundingRocket, @Spaceport_Cup
  • Send email to:

Themes to consider:

  • Updates specific to your team, test flights, fun build time-lapses
  • Fun tutorials on how you build, simulate, etc. (Keep it ITAR safe) 
  • Shorts on what you love about the event
  • Tips for new teams coming for the first time
  • Throwbacks and highlights to past SA Cup and IREC events
  • Team bios, or just a tour around your lab

Fine Print: Keep in mind all content is subject to review and not all may be posted. We may make minor changes to text as needed. In some cases, we may reach back with request for adjustments to your content. We may even request future collaborations with teams depending on the quality of the content. There is no promised timeline for posting. We will upload a backlog of posts, and depending on how much backlog we have, we will adjust the frequency of the scheduled posts. Initially we will do weekly, but eventually we would love to make daily posts. This does not give you bonus points for the competition. While you can reuse this content in any video challenges at the event, this is seperate from the video challenge. By submitting this footage you are giving us permission to post on the social media platforms above, and any possible future platforms. ESRA can also use footage in Youtube Videos, and Event Livestreams. ESRA acknologes that you own full rights to the media and we are not permmitted to sell or give rights to other persons or organizations.

Reminder - Issues that are created by Payloads that are deployed

Jan. 19, 2023, 12:06 p.m. PST by ESRA VP

Student Teams,

If your student team's payload remains within your rocket throughout your flight, you do not have to read any further.


If your payload is deployed at or above 5,000ft. it is a significant concern to ESRA.  


ESRA requires dual deploy recovery on all rockets.  We also require GPS tracking on all rockets.  Both of these requirements are necessary to help students quickly and easily recover their rockets.  With potentially 150 rocket launches, ESRA must limit the amount of time teams spend looking for rockets.


Your team COMPOUNDS this problem when you deploy a 2nd (or more) payload object from apogee or above 5k'.  More falling object increase risk and danger.  It also requires longer recovery times.  And it could lead to more lost rockets and payloads.

The number of ejecting payloads increases every year.  If this trend continues, ESRA will be forced to respond by further restricting or completely removing this option all together.


For 2023, ESRA Range Safety Officials will be spending significant more time evaluating ejected payloads.  Test flights and testing payload tracking should be included in all testing plan schedules.

Tripoli Rocketry Association Memorandum of Understanding for the Spaceport America Cup

Jan. 16, 2023, 8:55 p.m. PST by ESRA VP

The Experimental Sounding Rocket Association (ESRA) has entered into a Memorandum of Understanding (MOU) with the Tripoli Rocket Association (TRA) and Spaceport America (SPA). The agreement was signed and executed by ESRA President Cliff Olmsted, SPA Executive Director Scott McLaughlin and TRA President, Bob Brown. The MOU stipulates the adoption of rules and requirements for TRA membership and clearly explains who is covered by Tripoli insurance while participating in the Spaceport America Cup (SAC).

Key elements of the agreement are:

  • For the first time at SAC, hybrid flights which fully comply with the Tripoli Safety Code* will be covered by Tripoli insurance.
  • All flyers working on safety-related systems or present downrange must be active Tripoli members. This includes all 10k and 30k COTS/SRAD Solids and COTS/SRAD Hybrid flights. Liquid SRAD category rockets are not included in this MOU.  NAR membership does not meet this requirement.
  • Motors and energetic materials may only be possessed or handled by Tripoli members with appropriate high-power rocketry certification levels.   NAR membership does not meet this requirement.  NAR members must join TRA and have their certifications copied over.  This was agreed to by NAR President John Hochheimer and TRA President Bob Brown.
  • ESRA recommends student teams who have a NAR certified Flyer of Record should cover the cost of the TRA membership for their Flyer of Record.
  • Any Commercial Solid, Research Solid, Commercial Hybrid, or Research Hybrid flights must have a current Tripoli L3 certified member as Flyer of Record. Again, a NAR Certified Flyer of Record does not meet this requirement.  The Flyer of Record must be present at the launch. The Flyer of Record may be a student member, a team mentor, or other Tripoli L3 certified member as coordinated by ESRA.
  • The language of the MOU prohibits changes to the MOU within the last 30 days before or at the launch.
  • COTS and SRAD Hybrids and Solid rocket teams which do not fully comply with Tripoli Safety Code (described in the MOU as Non-Tripoli Safety Code Compliant) will not be approved to launch. Liquid category teams are solely responsible for arranging their own insurance in advance as per the ESRA Rules and Regulations.
  • Liquid category rockets will be segregated from all other operations and spectator areas by at least 1500 feet. Liquid launch operations shall be conducted by the student teams under ESRA coordination but different personnel than those operating ESRA's Launch Control Operations. The separation will be visibly and clearly marked.
  • ESRA will curtail all other launch operations when liquid category launches are underway.

A copy of the executed MOU will be available on the Tripoli website

ESRA has received multiple reports that Cesaroni Technologies (CTI) continues to experience serious component shortages and are unable to fulfill most orders for their high performance rocket motors (many 98mm reloads including the O3400 and N5800 motors).  

The delays mean that unless a team already has physical possession of their CTI motor(s), they are at serious risk of delayed delivery times (out to late summer).   Please understand that this issue affects the entire amateur high power rocketry community, and not just the Spaceport America Cup.

  • If your team has not placed an order for your rocket motor, your team is at extreme risk of not receiving one from any vendor.   
  • If your team has an order placed for a CTI motor, you should contact your motor vendor ASAP to seek clarity and confirmation on delivery dates. 
  • 30k COTS teams may downgrade to 10k (without penalty) if they are unable to secure an appropriate motor.  There are many more motor options that could be available for 10k launches.

ESRA's position on this issue is that we will do our best to recommend alternatives but your team is ultimately responsible for securing your rocket motor(s).  Aerotech does not appear to have any supply issues at this time.  More info coming soon.
